Products and services

2. Sensor Components

We are a leading supplier of CMOS MEMS Micro-Hotplates, and infrared sources and detectors, designed specifically for high performance, high stability gas and materials sensing, as well as other applications. Our Micro-Hotplates provide the key technology platform for chemical resistive and catalytic gas sensors. The infrared sources and detectors are used in a range of applications, including Non-Dispersive Infrared (NDIR) gas sensing, thermometer, spectroscopy, and Attenuated Total Reflectance (ATR) sensors for analysis of liquids and solids.

Infrared (IR) sources

Our infrared sources are available in a range of optical outputs, packaging options, as well as bare die and custom-made array solutions.

Infrared detectors

Our infrared detectors are still in development, for more information please contact


Micro-hotplates are available to customers for applications such as catalytic gas sensing and with Inter-Digitated Electrodes (IDE) for post-processing with metal oxide materials for resistive gas sensing applications. They are available in a range of packaging options, as well as bare die and custom-made array solutions for miniature multi-sensing applications.

In addition, our Micro-hotplates come with integrated FET drivers, where the heater temperature can be controlled by appropriately adjusting the gate or the supply voltage, therefore eliminating the need for a separate off-chip FET device. An integrated sensing diode also provides the benefit of accurately and independently monitoring the temperature of the heater, further improving sensor accuracy and lifetime stability.

1. Sensors

Our patented CMOS MEMS Micro-hotplates technology provides a unique silicon platform for our Metal Oxide (MOX) gas sensors and enables sensor miniaturisation, significantly lower power consumption and ultra-fast response times.

Our 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.

The CCS800 product family of ultra-low power gas sensor are supported in a compact 2mm x 3mm dual-flat no-leads (DFN) package as standard. Other package options including TO are available on request.
