Clever Battery Completes Stretchable Electronics Package

Northwestern University’s Yonggang Huang and the University of Illinois’ John A. Rogers are the first to demonstrate a stretchable lithium-ion battery — a flexible device capable of powering their innovative stretchable electronics.

No longer needing to be connected by a cord to an electrical outlet, the stretchable electronic devices now could be used anywhere, including inside the human body. The implantable electronics could monitor anything from brain waves to heart activity, succeeding where flat, rigid batteries would fail.

Huang and Rogers have demonstrated a battery that continues to work — powering a commercial light-emitting diode (LED) — even when stretched, folded, twisted and mounted on a human elbow. The battery can work for eight to nine hours before it needs recharging, which can be done wirelessly.

The new battery enables true integration of electronics and power into a small, stretchable package. Details are published by the online journal Nature Communications.

“We start with a lot of battery components side by side in a very small space, and we connect them with tightly packed, long wavy lines,” said Huang, a corresponding author of the paper. “These wires provide the flexibility. When we stretch the battery, the wavy interconnecting lines unfurl, much like yarn unspooling. And we can stretch the device a great deal and still have a working battery.”

Huang led the portion of the research focused on theory, design and modeling. He is the Joseph Cummings Professor of Civil and Environmental Engineering and Mechanical Engineering at Northwestern’s McCormick School of Engineering and Applied Science.

The power and voltage of the stretchable battery are similar to a conventional lithium-ion battery of the same size, but the flexible battery can stretch up to 300 percent of its original size and still function.

“Tumblr is so liberal because it’s mostly naive 14 year olds”

OH REALLY

LET’S CHECK

UH OH WHOOPS SOMEBODY’S SUPER WRONG

image
image
  • People under 17 are tumblr’s third SMALLEST demographic, barely more than people 55+
  • It has as many people 35-44 as 18-24
  • It has overall way more people over than under 24
  • Reddit’s overall average is just slightly younger

OOPS looks like the frequency of trans people on tumblr might not be bandwagoning kids

OOPS looks like tumblr’s feminist slant might actually be informed adults

OOPS looks like tolerance and progressiveness aren’t actually symptoms of youthful ignorance but what else could they be? Why else might tumblr seem a little more compassionate and accepting? IF ONLY THERE WAS SOMETHING ELSE TO GO BY

UH OH FUCKERS WHAT’S THIS

RxTimerCaps save lives. The clock resets to 00:00 every time the bottle is opened so I’ll know if I’ve missed a dose. I bought these online. by bionicback via reddit

They seem to be 2 for $15, and look really useful!

beautiful.

i just checked ALL of these on my calculator and they are all correct

all. fucking. correct.

DAYUM, SON! IF ONLY THIS WAS AVIALABLE WHEN I WAS ON SCHOOL >:(

HAH! You kids. When I was in school, it wouldn’t help because we still used Roman numerals back then!

AHAHAHAHAHA-

oh my god

i’ll just be over here shutting the fuck up right about now
