Wearable devices can help monitor people’s health as they go about their day, but existing ones are too rigid to maintain good skin contact. Naoji Matsuhisa, 32, has developed a stretchy diode made of thin rubber sheets that operates at frequencies as high as 13.56 megahertz, a frequency used for electronic wireless communication devices; previous stretchable semiconductor devices maxed out around 100 hertz. Whereas other stretchy circuits often involved embedding brittle electrical components into softer materials, Matsuhisa is making the components themselves flexible.
