Piezoresistive microcantilever optimization for uncooled infrared detection technology [PDF]

open access: yesSPIE 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 ...

A Low Spring Constant Piezoresistive Microcantilever for Biological Reagent Detection [PDF]

open access: yesMicromachines, 2020
This paper introduces a piezoresistive microcantilever with a low spring constant. The microcantilever was fabricated with titanium (Ti) as the piezoresistor, a low spring constant polyimide (PI) layer, and a thin silicon oxide (SiO2) layer as the top and bottom passive layers, respectively. Excellent mechanical performances with the spring constant of

High sensitivity piezoresistive cantilever sensor for biomolecular detection [PDF]

open access: yesJournal of Physics: Conference Series, 2006
Micro-cantilevers are now gaining popularity in biomolecular sensing. Monitoring and mass detection of biological species can be accurately determined using the micro- or nano- scale cantilevers. The targeted biological molecules are first immobilized onto the microcantilever which is later determined through static or dynamic techniques.
