Abstract:

Micro fabricated sensors based on the detection of nanomechanical motion are known to be promising for biochemical sensing. The use of conventional silicon based materials to fabricate microcantilevers results in a lower sensitivity and higher cost for the sensor depending on the Young’s modulus of the structural material, the geometrical dimensions, as well as the process complexity. UV patternable polymer materials such as SU-8 have a very low Young’s modulus compared to the silicon (Si) based materials, are cheaper, and show excellent promise as structural layers. In this talk, we discuss the progress made at IIT Bombay towards the development of a SU-8 microcantilever platform for sensing applications. The three approaches, namely the optical, piezo-resistive (with polysilicon films as well as with conductive nanoparticles dispersed in an epoxy matrix) and piezo-electric (based on a novel multi-ferroic material synthesized at IIT Bombay) read out schemes, have been implemented using a low-cost polymeric cantilever platform. We demonstrate practical applications involving these novel cantilever platforms for cardiac diagnostics and explosive detection.
