- Lets have a look inside the Freestyle Libre Sensor and what goes on inside. I've been using the system for about 10 months and think it definitely the future of glucose measurement.
Nice deep dive on the function of the sensor and the components used. Looking forward to the next analysis!
I have not done this ever. I like libre as it has eliminated frequent finger pricking from my life. which is very painful. Gradually I found libre is incomplete without a cgm device as every time scanning the sensor is not easy. I found Blucon Nightrider a third party cgm device which gives me sensor's reading every 5 minutes without scanning the sensor. Most important which I felt that every diabetic would like is that alarms. Blucon saved me on various occasions when my BS went too low and the sound alarms woke me up from sleep. Thanks to Blucon and libre sensor
Thanks for the video, I am using the NightRider with the LinkBluCon and there is no need to scan the sensor any more. I get reading updates every 5 minutes, alarms, and food insights. Food insights help me know how food I had impacted my glucose in next 3 hours, it helps me in choosing the right food. Also, all the premium features in the LinkBluCon app are free.
Sounds good!! I love my nightrider and use it 24/7. Also, love the ability to calibrate.
Do you do other products?!
I absolutely loved this video!! The data sheet, tracing the pins... that was really awesome!
Great video!Are you still working on the electrode inserter mechanism video?I would love to see how this neat technology all fits in together.
Kindly upload and keep up with the interesting videos!
I believe that Freestyle Libre 14 day is a snapshot reader-triggered measurement. The reader detects the trend (hence the arrows) to generate a graph based algorythm. The rise angle between previous scan can create false sense (based on my engineering statics 101 training) can throw the streight line flattening of the graph versus time.
Do you have a teardown video of the applicator?
Good teardown video.
Maybe you could try a small amount of petrol around the unit's seal. Wait 5 minutes and see if that helps opening on the sensor body.
I use this method on opening wallwart power supplies and laptop power supplies with great results. I just use a few drops out of my 4stroke lawn mower can.😁
Hi - i like the voltage doubler - VDDx2 - probably some insidous AC ladder. The new Libre 2 also has BT connection :)
I found this very useful, and I just wanted to say thanks! Very much appreciated!
Winner of a video, I have been researching "what test strips does the freestyle libre use" for a while now, and I think this has helped. Have you ever come across - Camebattian Mysterious Convenience - (should be on google have a look ) ? It is a good one of a kind product for discovering how to end your diabetes problem minus the headache. Ive heard some incredible things about it and my co-worker got excellent success with it.
Very nice, I have been using it from past one year with Blucon device. Also, I can reactivate my sensor for another 14 days with the help of Blucon device.
You are right, I am able to reactivate my sensor for more then 14 days with the help of my new blucon device.
@@shreyarastogi7303 Sounds Great!! I have BluCon NightRider and US Libre14 days. Can I reactivate US Libre 14 days?
very nice video , could you show us how the needle works, what is principle of sensor ?
Exact what I was looking for! 👍🏻
The other good thing about the meter that came with wifey's sensor (sample) is that you can buy regular sticks over the counter @ Walmart pretty cheap. We've got a problem with insurance not allowing any prescribing of sticks or her original meter over 3 / day, and since she's on a dual therapy, she needs 5 or maybe more / day.
Prime example of what annoys me the most. Anyway we can afford the OTC sticks to close out the shortage whether she gets this or not. Now checking what amount the INS will cover. This one leaves them no room for cover since they time out at a certain number of days, so they can't prescribe it all if they don't cover it fully.
Have you noticed your doc is for RF430FRL and the chip is RF430 TAL? I would guess it's more or less the same, but there might be a few mods. For instance, maybe there is no FRAM on board.
Excellent informative video. I"d like to see what is the sensor part is it just metal electrods or has something else inside. Thank you
Not sure what it is but it seems more like plastic. It's quite flexible.
I'm using my Libre sensor with Blucon NightRider. I'm very happy with the performance of the device. I'm using the new version of the Blucon which activates the new sensor for another 14 days.
Richra - a question - are you using it with Freestyle Libre Pro - if so do you still need Freestyle Libre Reader to *activate* - or only need the NightRider App, and the bit that clips onto sensor?
@@rajb4549 Yes, I am using BluCon with Freestyle Libre Pro and I activated the sensor through Libre activate app, there is no need for a reader. Also, I use 3D holder to protect my libre and blucon.
@@richakamra9207 Thanks for clarifying that. Is Libre Active App from Blucon. I am a T2 and so dont need continuous monitoring or alarms. I just want to track how what I consume affects my blood sugar. I only anticipate using it for say 2 months. So all I need is Libre Pro and the Libre Activate App?
Hi, any data about the sense electrode material used and its principle of working.Is this enzymatic or non enzymatic technology. and let us know what decides the validity (Eg:15 days for Freestyle Libre)
Great video, thank you! Is this a Libre 1 sensor?
These are NFC tags, so they could be reprogrammed to do anything or maybe even hack the sensor life?
do you think that is possible to change battery with another? A rechargeable one for ex.? And adding a circuit tu recharge wireless? Sorry for my noob questions.
Please do a applicator breakdown. Very interesting video. Thanks
This was great, I have been researching "will freestyle libre be available on nhs?" for a while now, and I think this has helped. You ever tried - Camebattian Mysterious Convenience - (do a search on google ) ? It is a smashing exclusive guide for discovering how to end your diabetes problem minus the normal expense. Ive heard some decent things about it and my m8 got amazing results with it.
Wonder if something as simple as pulling the battery and reconnecting would reset the clock. Not that I'd ever put it back on my arm.
It's definitely worth a try. I tried popping the triangular sensor out that actually goes in your body, hoping that that would power it down, but it doesn't. It remains powered up and the sensor stays in the failed state. Contact me if you know how to modify the firmware on this as I would like to try that:

Great video
It's a pity you can't install a new sensor on the board, it would save quite a bit of the products price.
ElecDIY I’d estimate there is less than $5 worth of electronics on the sensor. The sensor is $100 because of R&D, medical regulation and testing.
and profit
Intelectual property is a lie.
@@roidroid As in: Step 1: Collect underpants, Step 2: ...., Step 3: Profit! (if you didn't get this joke look up South Park's Underpants Gnomes....your very valid comment made me laugh as it reminded me of that episode of the show)
Why hasn't someone created
an app/technique that lets me
reset my FreeStyle Libre sensor
to get another 14 days out of it
WITHOUT me having to purchase
an expensive BluCon or MiaoMiao? 😕
Nice! Do you know if it is possible to reporpuse the circuit by reprogramming the microcontroller. Thank you!
It really helped me a lot but it was very expensive for me. my dream and find a safe way to reuse
So why these sensor work and approved by government only for 10-14 day usage. What is stopping making/hacking this sensor for longer use? Battery can be solved...
I was wondering if we can hack it's nfc and replace it with Bluetooth and if this can be reused to be honet.
Hello, given the size and construction of the device, hacking would be difficult, however, look for BluCon or Sony Smartwatch 3 hacks to convert the Libre into a continuous reader when paired with a smartphone in range.
are you currently using the device? If you are India, how did you get it?
Have a look here: github.com/JoernL/LimiTTer this is a NFC to bluetooth adapter for freestyle libre, I might build one myself...
@@himanshujain5674 Hi kindly provide your number, we have reseller in India, they will contact you.
I understand that a newer version of the 14 day sensor is bluetooth enabled.
Não há como não usá-lo por mais de 14 dias? o sensor certamente dura muito mais que isso. o software que está programado para parar em 14 dias .. Estou lendo no celular pelo soft do mesmo Libre. Fiz um teste quando faltava 1 minuto para terminar o prazo, depois fiz outro teste com a fita e eles bateram o mesmo, ou seja, o sensor após 1 minuto iria se deteriorar? certamente não . Como podemos resolver isso?
Talvez a limitação esteja na bateria.
Why these sensors need to be replaced every 14 days? What happens to these sensors after 14 days?
Accuracy declines towards the end, and increased scarring if leaving in for longer. Abbott has made it to stop working at 14days so there is no point keeping it in beyond that.
wonderingif it is possible to reset the timer in the chip. or it is the sensor made in that way?
wow! so helpful! thanks!
Hi nice video! Do you know how many voltage the batterie have?
1.5 V
i'm student and i'm taking some research about sensors speacially on medical sensor and their cost
i can't find any thing about this sensor that use in glucose measurement ( their datasheat )....
Pages 100 to 125 on the owners manual
Why do you have to throw this away after 2 Weeks? There is a whole lot of technology in the sensor, that could be reused.
You dont have to through iz away but you should stop using it. At your arm.
Yep! It could even be hacked with an NFC tag writer to extend the life of it to 3, 4, or even 5 weeks, or format it to use it for something else
Will it blend?
Hello,
changing the battery sensor,it can be reused and is fully functional, or is it not calibrated?
The battery still has heaps of charge left after the 2 weeks, sensor expiry is done artificially either through the reader or sensor.
Reuse is mainly limited by the fact that you can't re-insert a used sensor (not that you'd want to), the electrode part that goes into the skin also may degrade and be less effective after the 2 weeks.
It is programmed to turn off after the two weeks. Much like the chips in ink jet cartridges. Keeps you coming back to buy more.
Can it be avoided?
Does the board have conformal coating?
As I remember it doesn't, I was able to probe the board once opening. The outer case is sealed to prevent water entry.
Thanks! I saw another video recently that made it seem as though they do. I'll crack mine open soon and see what the situation looks like. I wonder if it's a region-specific treatment. @@lightnthings5541
It would be nice to be able to resset the sensor to be able tu use 1 one the month ! we are not all rich.. :( still hope somone to make some app to reset 14 days to 30 days longer ..
10:45 - these frames intentionally left black :)
We have had one (wifey uses it) sampled to her by a doc. When we installed it it bled out of the weephole quite a bit. When we quizzed the doc about it bleeding, he said that it should not bleed at all. No idea how a spike this deep wouldn't bleed. I've personally had much shallower spikes (metal shavings, etc.) that stuck me on my foot and it got to blood. This thing goes in at least 3/4 as deep as her injector pin does.
Anyone have that happen? what to do? Next time I'll have the video going to show the doc anyway. He claimed a lot of patients and no blood. I a doubting it.
Will have to tear up the one we have and see if there's any hacking possible. Wish foone had one to get doom running on it :-)
It does happen, and that's totally normal for it to bleed from that place.
Source: I've been using it for 3+ years.
For me it bleeds if I insert it with force....if I apply it gently, it doesn't bleed
@@renus6015 there's a 3/8 inch spiike that lances you. Has a path up thru center.
Force of application was a function of the applicator. Just released it, and bleed out the hole on top.
Endo guy said it shouldn't bleed either, but when it had expired ans she saw him next sent the thing in with spike out
Am I right in saying then that the Libre FreeStyle has no memory? It takes a reading when the NFC field is activated, sends data and the connection closes?
No.It has FRAM & RAM Memory.To store 15 min tagged values.
donde lo puedo conprar en mexico
@@jkengg Does it not store 8h values?
@@susimpantoja860 Comprar en Costco en Mexico. Los pricios para dos sensores en enero 2022 fue $ 2,500 MXN.
It was difficult to watch this video. Your voice is too passive and I almost fell asleep listening to this.
Depends on which links are implanted in your neural Interface. Mine are working perfect, i can condense all my neuroRAM for comprehension until the end of video. ✌️🤓👍
