LeGoff was previously CEO of Plessey Semiconductors Ltd. (Plymouth, England) until he resigned in 2018 (see Plessey CEO in shock resignation). Former Sorex Sensors CEO John Pritchard will continue with the company in an advisory role until mid-April.

Sorex Sensors was founded in 2017 by Professor Andrew Flewitt, Mario de Miguel-Ramos and Professor Bill Milne from Cambridge with co-founders Marina Cole and Professor Julian Gardner from the University of Warwick and Professor Enrique Iborra from the Universidad Politécnica de Madrid.

The company has developed a mass sensor that is based on film bulk acoustic resonator (FBAR) technology. The advantages over existing sensors include: sensitivity down to 1 femtogram; small size due to CMOS compatibility and low power consumption allowing coin cell battery and energy harvesting operation.

Sorex raised £1.2 million in June 2018 from Cambridge Enterprise, the Cambridge Angels and Cambridge Capital Group.

FBARs are already in manufacture using standard CMOS processes for use as filters nd multiplexers in telecoms applications. Sorex is focusing on film thickness measurement in deposition systems, particle monitoring and specific gas molecule sensing in consumer goods although there are potential applications in explosive detection and biological and medical fields.

“We are now focusing on a few key industrial applications where the technology will have an immediate and tangible impact, creating real demand. It’s great to be involved in a business where the path to scale production is relatively clear,” LeGoff is quoted saying.
