Stretchable Electronics
-
Besides having tentacles, squid and octopi are also both known for their color-changing skin. Well, soft-bodied robots may soon also share that attribute, thanks to research being carried out at Cornell University.
-
Before things like touch-sensitive robot skin can become commonplace, we first need to develop robust and reliable flexible electronics. Researchers have taken a big step toward that goal, by developing circuits that remain functioning while being stretched by up to four times their original length.
-
Before flexible electronic devices can become commonplace, there needs to be a practical way of manufacturing reliable stretchable circuitry. While some solutions are already in development, Panasonic recently announced one of its own – a flexible polymer resin film.
-
We generally picture lasers as being encased within hard housings, much like most other electronics. Thanks to new research, however, we could soon see sensors or other devices that incorporate stretchable laser-emitting rubber.
-
By wrapping a rubber core in carbon nanotube sheets while stretched, scientists have been able to create a conducting fiber that stretches like an accordion. It could find application in exoskeleton limbs, morphing aircraft, and more.
-
ScienceA new conductive, transparent, and stretchable nanomaterial that folds up like an accordion could one day be applied to the development of flexible electronics and wearable sensors, as well as stretchable displays.

A new nanoparticle liquid metal ink promises faster, cheaper, and easier production of stretchable, bendable electronics for clothing, soft robotics, and wearable devices created directly from an ink-jet printer.
-
ScienceIf flexible electronic devices are ever going to become practical for real-world use, the circuitry incorporated into them will have to be tough and resilient. With that in mind, scientists have created optical circuits utilizing the world's first stretchable optical interconnections.

In 2012, Dr. Yong Zhu and a team at North Carolina State University created highly conductive and elastic conductors made from silver nanowires. Two years later, the NC State researchers have developed a wearable, multifunctional sensor using the technology.
-
ScienceScientists at the New Jersey Institute of Technology have created prototype flexible batteries. Designed for use in electronic devices with flexible displays, they could conceivably be manufactured in any size or shape, or even made at home.
-
Scientists have developed a stretchable lithium-ion battery, that could be used to power stretchable electronic devices.
