A multi-institutional research team has developed a new electroactive polymer material that can change shape and size when exposed to a relatively small electric field. The advance overcomes two longstanding challenges regarding the use of electroactive polymers to develop new devices, opening the door to a suite of applications ranging from microrobotics to designer haptic, optic, microfluidic and wearable technologies.
Engineers have developed a cloaking device for microscopic photonic integrated devices - the building blocks of photonic computer chips that run on light instead of electrical current - in an effort to make future chips smaller, faster and consume much less power.
With a thickness of just 1.3 nanometers - 10 times smaller than the current standard silicon diodes - this device could be used in the Internet of Things, smart devices, wearable electronics and photoelectronics.
The risk of catching fatal Legionnaires' disease from air conditioning units has been dramatically reduced, thanks to a new biophotonic light sensor that spots Legionella bacteria 240 times quicker than methods used today.
Researchers are running structural studies using extensive numerical simulations on a supercomputer to study the motion of more than 500 atoms - in an effort to determine the forces on each atom and the total energy via density functional calculations.
With size comparable to a blood cell, those tiny robots have the potential to be injected into patients' bodies, helping surgeons to remove tumors and enabling more precise engineering of targeted medications.
Researchers have combined one of nature's tiny miracles, the diatom, with a version of inkjet printing and optical sensing to create an exceptional sensing device that may be up to 10 million times more sensitive than some other commonly used approaches.
Engineers have fabricated the first semiconductor-free, optically-controlled microelectronic device. Using metamaterials, engineers were able to build a microscale device that shows a 1,000 percent increase in conductivity when activated by low voltage and a low power laser.
