Paper Abstract

Broadband IR radiation detectors have been developed using miniature, inexpensive, mass produced microcantilevers capable of detecting temperature differences as small as 10-6 K. Microcantilevers made out of semiconductor materials with dimensions of 50 to 200 micrometers long, 10 to 30 micrometers wide and 0.4 to 4 micrometers thick, undergo bending when exposed to IR radiation and can be used either as uncooled photon or thermal detectors. Mounted on a probe 1 mm in diameter a number of microcantilevers can be accommodated in the working channel of existing endoscopes for in vivo proximity focus measurements inside the human body.
