MEMS spectrometer promises mobile, wearable chemical sensing

February 06, 2018 // By Peter Clarke
A MEMS-based ion mobility spectrometer developed at University California, Davis, has been licensed to SensIT Ventures Inc. (Davis, CA), a developer of chemical sensors.

The ion mobility spectrometer can be used to identify a broad range of chemicals in environmental samples and does so at a fraction of the size, weight and power requirements of traditional detection instruments, UC Davis claims.

The miniaturization and reduction in power consumption allows for increased use and has the potential to be integrated into smartphones and wearable devices. Potential applications enabled by the technology include detecting explosives, plant diseases, and environmental triggers for asthma.

The technology was developed by a team led by Professor Cristina Davis (pictured) in the Bioinstrumentation and BioMEMS Laboratory at UC Davis. Davis is also chief scientist and co-founder of SensIT.

SensIT Ventures Inc. was founded in 2015 to utilize proprietary technology to develop, build and sell custom chemical sensors.

"SensIT currently has multiple contracts, bids, and grant proposals pending to serve different initial customers in multiple markets. We expect to close our first contracts in 2018," said Tom Turpen, CEO of SensIT.
