Core Technology

Lightsense has developed a technology platform for a new generation of infrared sensors that are highly accurate, have long term stability and require low power so that they can be powered by energy harvesting. This technology platform can be used to make a variety of sensors for environmental analysis and monitoring, as well as health monitoring.

The core technology of Lightsense is a new class of MEMS (Micro Electro Mechanical System) devices combining proprietary thin film materials and silicon processing. This technology is used to produce high-performance components for infrared absorption spectroscopy, both single gas sensors and miniaturized full spectrum infrared spectrometers covering the mid-IR range from 2.5 µm up to 12 µm that can be used to analyze gases, liquids or solids.

Proprietary MEMS technology:  Lightsense IR MEMS chips incorporate unique and proprietary thin-film materials incorporated into devices produced with the same silicon processes used for microelectronics

All molecules have unique infrared “fingerprints” in the mid-IR range. This allows us to determine the composition of any liquid, solid or gas. IR detection combines a high degree of accuracy and sensitivity.

Absorption spectra for five gases in the mid-infrared region of he spectrum illustrate the fingerprint nature of the IR spectrum where different compounds can readily be distinguished by detecting one of a limited number of wavelengths
