ElFys provides light sensors with better sensitivity than anything seen before, literally catching every ray of light. The technology greatly improves any light sensing application ranging from health monitoring to analytical instrumentation and security X-ray imaging. The superior performance of ElFys photodetectors is based on an inventive combination of modern MEMS nanotechnology and atomic layer deposition. The core technologies are patented and in the possession of the company. The company utilizes the state-of-the-art processing facilities at Micronova Nanofabrication Center in Finland: 2600 square meters of CMOS compatible facilities suitable for both R&D and semi-mass production. For high-volume mass production, ElFys is working together with an external foundry partner.
