Fiso Technologies

What Fiso Technologies does

FISO Technologies Inc., founded in 1994 and headquartered in Quebec, Canada, is a developer and manufacturer of fiber optic sensors and signal conditioners. The company is a wholly-owned subsidiary of Resonetics and operates the Nortech and Sensornet sub-brands alongside the core FISO product line. Its core technology is built on Fabry-Perot interferometry for pressure sensing and GaAs (gallium arsenide) semiconductor-based temperature detection, with MOMS (Micro-Opto Mechanical System) fabrication enabling ultra-miniature sensors down to 200 microns in diameter. The product portfolio includes fiber optic sensors for temperature, pressure, strain, displacement, and refractive index; the EasyGrid family of transformer temperature monitors; the FOP-M200/M260/MIV medical pressure transducers; and the FPI-LS module with Evolution software for life sciences applications.

FISO generates revenue primarily through hardware sales of sensors and signal conditioners, supplemented by one-time software licenses for supporting applications. The business is organized around three primary verticals: medical devices (sensors integrated into FDA, CE, CFDA, and PMDA approved devices), energy and power utilities (transformer hot-spot monitoring via the EasyGrid line and DTS systems inherited from Sensornet), and life sciences (preclinical and MRI-compatible pressure measurement). A developing e-mobility/automotive vertical targets EV battery thermal management R&D. Go-to-market is a hybrid enterprise field sales model with a direct sales team in Quebec and regional specialists in Asia, Latin America, and Europe, combined with a global distributor and representative network covering more than 75 countries; an OEM/embedded channel sells signal conditioner modules to medical device manufacturers for integration into patient monitoring consoles. Pricing is not publicly disclosed and is presumed to be quote-based given the application-specific, B2B enterprise nature of the products. The company holds ISO 9001:2015 and ISO 13485:2016 certifications (BSI Group, since 2003) and manufactures at scale, producing hundreds of thousands of sensors and thousands of signal conditioners annually.
