[Abstract]

Heterogeneous integration and 3D integrated electronics/optoelectronics can lead to disruptive improvement in IoT devices. Conventionally, wireless electronic skins rely on rigid integrated circuit chips that compromise the overall flexibility and consume considerable power. I will talk about a chip-less wireless e-skin based on surface acoustic wave sensors made of freestanding ultrathin single-crystalline piezoelectric gallium nitride membranes. Surface acoustic wave-based e-skin offers highly sensitive, low-power, and long-term sensing of strain, ultraviolet light, and ion concentrations in sweat. Also, hemispherical image sensors based on organic semiconductors and photolithography processes are introduced. Our organic hemispherical image sensor array shows the best responsivity for similar dark currents among all the reported hemispherical image sensor arrays to date.
