Chip-less wireless electronic skins by remote epitaxial freestanding compound semiconductors

Yeongin Kim et al.

Summary: Recent advances in flexible and stretchable electronics have led to the development of electronic skin (e-skin)based health monitoring platforms. Conventional wireless e-skins use rigid integrated circuit chips, while chip-less wireless e-skins use surface acoustic wave sensors made of piezoelectric materials, which offer highly sensitive, low-power, and long-term sensing capabilities for monitoring strain, ultraviolet light, and ion concentrations in sweat. These findings provide new routes for creating inexpensive and versatile wireless health monitoring devices.
