Interlink Electronics Inc (NASDAQ: LINK) is a sensing technology company that designs and manufactures force/touch sensors, electrochemical gas sensors, rugged human-machine interface devices, and printed electronics solutions for HMI and IoT applications. Revenue comes from transactional product sales of components and integrated systems, supplemented by custom engineering services and government-funded Small Business Innovation Research grants from agencies including NIST, NASA, NIH, USDA, NSF, and EPA. The company operates across two technology platforms: Force/Touch Sensing and HMI Solutions. It expanded its capabilities through four acquisitions completed within three years prior to the FY2025 filing: SPEC, KWJ, Calman (2023), and Conductive Transfers Limited (2024), adding membrane keypads, graphic overlays, conductive textiles, and industrial labeling to its portfolio. Interlink competes against legacy switch technologies and commoditized capacitive sensors in force/touch sensing, and against established electrochemical sensor makers in gas sensing. The company does not pay a cash dividend on common stock as of the FY2025 10-K filing date.

Revenue model

Transactional product sales of sensors, instruments, rugged HMI devices, and integrated systems; custom design and engineering service fees; government SBIR grant funding for in-house research and development.

Products and services

FSR® force-sensing resistors (including FSR X® and FSR UX® families), piezoelectric sensors, electrochemical gas and environmental sensors, rugged HMI interface devices, wearable and textile-based sensors, membrane keypads, graphic overlays, conductive textiles, industrial labeling, integrated printed electronic systems, custom gas-sensing modules, calibration and compensation instruments.

Customers and end markets

Customers range from startups to Fortune 500 companies. End markets include automotive vehicle entry and control systems, industrial interfaces, medical interfaces, wearable monitoring, IoT applications, wildfire air pollution monitoring, firefighter safety systems, transdermal alcohol detection, drinking water lead detection, and generator carbon monoxide shutoff systems. Government research agencies are also customers via SBIR grants.

Value-chain role

Vertically integrated component and subsystem supplier. Designs and manufactures sensors and instruments in-house (electrochemical sensors fabricated in Fremont, California), provides end-to-end custom engineering services, and sells components and integrated solutions directly into customers' product designs. Collaborates with research institutions including Georgia Institute of Technology, San Jose State University, and UC Davis on government-funded programs.

Geographic exposure

Manufacturing and engineering operations in Fremont, California. Filing describes global customer reach but does not disclose specific revenue breakdowns by geography in the excerpts provided.

Competitors
