What Sensor Technology does
Sensor Technology Ltd, operating as Sensortech Canada, is a Canadian designer and manufacturer of piezoelectric ceramic (PZT) materials and underwater acoustic sensors headquartered in Collingwood, Ontario. Founded in 1983 by Eswar and Shashi Prasad and owned since 2011 by President and CEO Niru Somayajula following a management buyout, the company operates three Canadian facilities spanning Ontario (powder formulation, ceramic pressing, finished sensor assembly) and Dartmouth, Nova Scotia (hydrophone/transducer manufacturing plus an Advanced Sonar R&D site for electronics and firmware). Its core offerings are proprietary Hard PZT, Soft PZT and Modified Lead Titanate ceramic components in sizes from 2 mm tubes to 178 mm bars, assembled into hydrophones and acoustic transducers for defense, oceanography, aquaculture, hydrography and offshore energy customers.
The company's business model is built on custom, quote-based hardware sales to enterprise buyers, with batch sizes ranging from 5-piece prototypes to 50,000-piece production runs and multi-year production contracts. Go-to-market is enterprise field sales, executed through direct engagement with defense prime contractors and government agencies, supported by an active trade show presence at events such as CANSEC, UDT, DEFSEC, Oceanology International and Blue Innovation Symposium, plus technical content marketing through its Knowledge Hub and blog. Manufacturing is vertically integrated under an ISO 9001:2015 quality management system with full lot and serial traceability back to raw piezoelectric powder inputs, and proprietary PZT formulations are qualified to Canadian, US and global navy standards.
Customer mix is led by naval defense (hull-mounted sonar, mine countermeasures, sonobuoys, towed arrays, anti-torpedo and dipping sonar), with secondary exposure to offshore energy, aquaculture, oceanographic research and hydrographic survey sectors. The company has secured repeated non-dilutive Canadian government funding (FedDev Ontario, ACOA, Canada's Ocean Supercluster) cumulatively approaching CAD $9.3 million across 2021-2026, and is investing in miniaturized acoustic sensors for unmanned underwater, surface and aerial vehicles, positioning for the autonomous maritime platform market.

Sensor Technology product offering
Product offeringCore offering
Sensor Technology Ltd custom-manufactures piezoelectric ceramic (PZT) components — including Hard PZT, Soft PZT, and Modified Lead Titanate formulations in sizes from 2 mm tubes to 178 mm bars — and assembles finished underwater acoustic devices including hydrophones and acoustic transducers for naval defense, oceanography, aquaculture, offshore energy, and hydrography applications. Production runs span from 5-piece prototype batches to 50,000-piece production volumes, with all ceramics qualified to Canadian/US and global navy standards and manufactured under an ISO 9001:2015 quality system.
Product overview
Sensor Technology Ltd is a manufacturer of underwater acoustic technology components and systems. The product portfolio centers on three core offerings: (1) Piezoelectric Ceramics (PZT) in Hard PZT, Soft PZT, and Modified Lead Titanate formulations, serving as the fundamental material component for all acoustic products; (2) Hydrophones, which are acoustic receivers used for underwater sound detection across multiple sectors including defence, oceanography, aquaculture, and energy; and (3) Acoustic Transducers, which are acoustic transmitters and transceivers for naval defence, hydrography, and oceanography applications. The company also offers Acoustic Sensors and Acoustic Systems as product categories. All ceramic formulations are proprietary and manufactured in-house, with all formulations meeting navy standards for Canada/US and global markets.
