Micro-electro-mechanical silicon resonators have been seen as a promising alternative to quartz for timing control applications, and have also received much interest for realizing high-sensitivity micro sensors based on the principle of modulating mechanical resonance. This talk will discuss and explore their application to the measurement of mass as well as charge (electrometers), beginning with a survey of areas where charge and mass sensing have...

Michael Cohen runs the UC Berkeley office that is responsible for leveraging the University's intellectual property (IP) in order to help catalyze the commercialization of Berkeley innovations, and promote the funding of campus research. In this role, Michael leads initiatives that include working with researchers and attorneys to patent technology, and collaborating with companies, entrepreneurs and investors to license...

Power sources for integrated electronics have been a growing concern with the ever-increasing use of portable devices. Recent advancements in "smart" materials have led scientists to explore the application of these materials for energy harvesting applications. An especially promising material is the Ionic Polymer-Metal Composite (IPMC). In 1993, Oguro et al. found that a perfluorinated sulfonate membrane sandwiched between platinum electrodes...

Microsystems can offer new and convenient ways to interact with biological systems in vivo and in vitro and our lab. is constructing some building blocks from component technology (such the"flexible CMOS") to MEMS-inside systems (such as a "nanoMRI") to facilitate these interaction. For the former, I'll use the example of a flexible 8" 0.18um Mixed Signal/RF CMOS circuit technology for medical implant applications. CMOS silicon substrate is...
