We have recently made an investment in Cambridge CMOS Sensors for the Parkwalk Opportunities EIS Fund and the University of Cambridge Enterprise Fund III.. This follows predecessor funds investing in 2012 and 2013.

Cambridge CMOS Sensors is a leading manufacturer of sensor solutions for monitoring air quality, with a wide range of miniature, ultra-low power gas sensors based on metal-oxide technology and infrared sensor components.
Cambridge CMOS Sensors is a spin-out from University of Cambridge and is exploiting innovative patented technology jointly developed in collaboration with the University of Warwick. The company aims to be a technology provider of CMOS MEMS structures such as basic and smart micro-hotplates, semiconductor sensors (gas sensors, mechanical sensors, temperature sensors & flow sensors) and nano-MEMS and nanosensors and a leading manufacturer of mid-infrared emitter.
CMOS MEMS platform technology provides a unique silicon platform for CCMOSS’ Metal Oxide (MOX) gas sensors and enables sensor miniaturisation, significantly lower power consumption and ultra-fast response times.
The Micro-hotplates are suspended in a high reliability membrane and act as heater elements for a metal oxide based sensing material. The material resistance will change due to reactions to selected gases and concentrations at temperatures between 200°C to 400°C. Through enabling very fast cycle times, advanced temperature modulation techniques can be used to ensure maximum sensitivity, stability and gas selectivity and minimise measurement times.
Advanced algorithms support the MOX gas sensors family, for maximum selectivity, drift compensation and for self-calibration, enabling easy and timely integration into a wide range of applications.
