Yichen Cai, a materials scientist at the King Abdullah University of Science and Technology in Thuwal, Saudi Arabia, is creating a thin, skin-like film that can change the way wearables are tested, used, and designed. Nature shares her work.
I am a materials scientist at the King Abdullah University of Science and Technology (KAUST) in Thuwal, Saudi Arabia, and my work involves creating thin, flexible, conductive films that mimic human skin. This ‘e-skin’ has many potential applications, especially in health care, where it can be used to build wearable sensors to measure things such as blood pressure, movement and body temperature. It could also allow robots to sense touch, like humans do, or deliver drugs into the body.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
