Biomimetic Optical Sensing Systems (BOSS)
While conventional optical sensing devices such as CCD and CMOS imagers are planar in geometry, the imagers in nature are different. Fruit flies have spherical compound eyes and human has spherical retinal. The project aimed to develop a biomimetic optical sensing system (BOSS) by combing the state-of-the art IC fabrication technologies and the elastomer engineering techniques. We have demonstrated the following proof-of-concept works:
1. Post-CMOS processing compatible fabrication methods to integrate photodetectors with the elastomer.
2. Electrical connection methods on a tunable spherical membrane using MEMS flexure.
The project is currently seeking funding to support prototyping the imager using PDMS elastomer with integrated MSM Poly-Si photodetectors.
