High time for IR sensor 2.0

The IR sensor is a crucial component in many products, ranging from medical equipment to mobile phones. However, the technology is 50 years old and in serious need of an upgrade. The next-generation IR sensor 2.0 for IoT will be much thinner than the old sensors, and cheaper to make.

Stretchable electronics – still a way to go yet

Stretchable electronic components that already exist are conductors and electrodes made from silver nanowires and graphene. However, what’s urgently needed are stretchable energy conversion and storage devices, such as batteries.

Researchers develop a graphene-based sensor that can detect the brain’s low-frequency signals

A newly-developed graphene-based implant can record electrical activity in the brain at extremely low frequencies and over large areas, unlocking the wealth of information found below 0.1Hz.
