Flexible Conformal Micromachined Absolute Pressure Sensors

Journal of Microelectromechanical Systems, 2015
The fabrication and characterization of micromachined piezoresistive absolute pressure sensors in a flexible substrate is presented. A suspended aluminum oxide diaphragm containing nichrome (Ni-80%/Cr-20%) piezoresistive sensors backed by a vacuum cavity was utilized to form the sensor.

Transparent, Flexible, Conformal Capacitive Pressure Sensors with Nanoparticles

Small, 2018
AbstractThe fundamental challenge in designing transparent pressure sensors is the ideal combination of high optical transparency and high pressure sensitivity. Satisfying these competing demands is commonly achieved by a compromise between the transparency and usage of a patterned dielectric surface, which increases pressure sensitivity, but decreases
