Stretchy electronics go wireless

- Flexible electronics offer a lot of potential benefits to the design of wearable technology, but previous intrinsically stretchable semiconductors haven’t been able to meet the strict requirements for the high-frequency operation needed for many useful applications.
Now a team of researchers have developed a new polymer diode that is stretchable and operates at high enough frequency to unlock wireless operation and power.

How these components don't dramatically change their electronic properties when being stretched, bent and distorted is beyond me. Very impressive.
I am really glad these videos exist; showing some of the newest developments in science that might become mainstream in the years to come.
1:43 "Bluetooth low energy", which many current wearables use, is 2.4 GHz. So this 13.56 Mhz hasn't quite enabled that, but it's still a big step up.
Now I know what softwear means
Well done!
신기하네요! 신축성이 있어서 불편 하지 않을 꺼 같아요! 좋은 정보 감사합니다.^^
I love it that is so impressive 💕
Explanation please Nature? Conductors are typically metals. So what’s going on here? Saying it’s ‘stretchy’ a dozen times does not make much of a science video.
Conductor are typically metals this stem from the fact that metals have a little diference between valence band and conduction band (band where electrons move) so, little diference means better conduction of current. In an organic polymer this behavior can be modulated by playing with HOMO and LUMO orbitals (these would be like the valence and conduction band in metal). And if the polymer is conjugated (it means that the chain of the polymers is made of a Electronic Bridge that enable the move of electron throughout the whole polymers you could have a conductor material based on organic molecules. And as you can see. Polymers are flexible so the Word natural love in this video "stretchy". I hope this help you and apologies for my english I am from colombia (spanish speaker).
@@EdwinGonzalez-vs9el Thank you sir, very clear, as far as it goes. If only you were narrating for Nature instead of this “stretchy” guy. The big step here, it seems to me, is explaining how one “plays” with orbitals in an organic molecule without making it not what it is.
And, if that’s too big a step for a 1 min Nature video, then say so in the video.
@@Nill757 each organic molecule has a band gap (this is the difference between HOMO and LUMO orbitals). For example. Molecules that absorbs and emits red light have a little band gap, since red light is less energetic than blue for example. So we could modulate the band gap of a molecule with the introduction of elecreonegative elements/funcional groups or with the extension of the conjugation.
However, having a big band gap in a molecule is not bad. Everything depends on the applications of the system. Maybe a researcher wants to build a device that emits blue light. So for him, a bigger band gap to absorb and emits blue light is excelent.
@@EdwinGonzalez-vs9el Interesting. Thanks. I’m an EE, aware of the BG, but didn’t realize the atomic gap could be changed by other atoms in a molecule. Should have known, since molecules absorb different wavelengths than do their elemental components.
Yesss
T-1000. Soon ....
Soft + wearable= software able
Being articulate in scientific communication isn't one of his strong skills.
Yeah, half way in the video I realized he was "speaking english"... XD
@@Reth_Hard It's so sad because his invention is so important. But because he can't convey knowledge efficiently, the invention won't reach outside of labs.
Dont be rude to him for his english. You can see he is trying and his lack of english speaking proficiency has nothing to do with his scientific communication skills. In fact, i think it is the video publisher's fault for not including subtitles.

I don't know about monka but I'm not joking, for a bit I really wasn't sure if he was speaking English or Chinese!
And I do know how difficult it is to speak a second language, I'm French-Canadian... I don't really have too much difficulties for reading and writing but speaking is really something else, especially if you don't do it on a regular basis...
@@Reth_Hard Prof. Matsuhisa is not even Chinese. If you have a problem understanding his accent, try exposing yourself to more English accents there are out there. The fact that he does not speak in a transatlantic accent that speaks nothing about his communication skills.
