Contact Mode MEMS Position Sensors with Piezoresistive Detection

Procedia Engineering, 2014
Abstract Measuring of linear position with contact MEMS sensors is a promising option for achieving sub-nm resolution, as demanded by micro-/nanotechnology community [1] . The position of specific point of interest can be calculated by bending detection of cantilevers or more complex MEMS flexures via different techniques: optical, capacitive ...

Piezoresistive microcantilever optimization for uncooled infrared detection technology [PDF]

SPIE Proceedings, 1996
Uncooled infrared sensors are significant in a number of scientific and technological applications. A new approach to uncooled infrared detectors has been developed using piezoresistive microcantilevers coated with thermal energy absorbing materials. Infrared radiation absorbed by the microcantilever detector can be sensitively detected as changes in ...
