Interlink Electronics Inc (NASDAQ: LINK)

Interlink Electronics Inc is a global provider of advanced sensing technologies and printed electronics solutions that enable Human-Machine Interface (HMI) devices and Internet-of-Things (IoT) applications. The company offers a broad portfolio of products and technologies, including force and touch sensors, piezoelectric sensors, rugged HMI sensors, wearable and textile-based sensors, and electrochemical gas and environmental sensors. Interlink also provides instruments and fully integrated systems based on its sensor technologies, catering to diverse end-use markets such as medical, industrial, automotive, consumer electronics, wearables, environmental monitoring, and specialty applications.

Interlink generates revenue through the design, development, manufacture, and sale of its sensing technologies and integrated systems. The company's primary products include FSR® (Force-Sensing Resistor) technology, HMI technology platforms, printed electronics and membrane keypads, smart textiles and conductive transfers, piezoelectric sensors, and gas and environmental sensors. These products are sold to a global customer base comprising blue-chip companies and innovative emerging firms across various industries. Interlink's technical and engineering expertise in materials science, printed electronics manufacturing, embedded electronics, and related firmware, software, and system integration allows it to deliver high-performance, cost-effective standard and custom solutions tailored to customers' unique requirements.

• Force/Touch Sensors: Interlink designs, develops, manufactures, and sells a broad range of force-sensing and HMI technologies that incorporate proprietary materials, firmware, and software into scalable sensor components, subassemblies, modules, and fully integrated products. The company's FSR® technology and force-sensing leadership are pivotal in this segment, offering rugged and reliable HMI applications. Interlink's HMI technology platforms are deployed across medical, industrial, automotive, and consumer electronics markets, supporting applications such as vehicle entry and cockpit controls, multimedia interface systems, rugged industrial touch controls, presence and collision detection, speed and torque control systems, pressure mapping, and biological monitoring. The company's printed electronics and membrane keypads capabilities, enhanced through the acquisition of Calman Technology Limited, cater to industrial automation, instrumentation, process control, medical diagnostics, and defense applications.

• Smart Textiles and Conductive Transfers: Through the acquisition of Conductive Transfers Limited and Global Print Solutions Limited, Interlink has strengthened its patented conductive transfer processes. This segment enables the integration of sensors and electronics directly into textiles and fabrics, catering to markets such as heated garments, personal protective equipment, medical wearable platforms, and automotive-integrated textile sensing systems.

• Piezoelectric Sensors: Interlink has expanded its sensing portfolio with piezoelectric polymer film technologies that function as dynamic strain gauges and vibration sensors. These ultra-thin electroactive polymer films generate electrical charge when subjected to mechanical stress or temperature change, catering to applications in dynamic force and vibration sensing, impact detection, contact microphones, flow detection, ultrasonic transducers, and motion and vital sign monitoring.

• Gas and Environmental Sensors: Interlink entered the gas and environmental sensing market through the acquisition of SPEC Sensors, LLC and KWJ Engineering, Inc. This segment offers electrochemical gas-sensing products and integrated systems for safety, environmental monitoring, industrial compliance, community health, and smart city applications. The company's proprietary product lines include miniature, low-power electrochemical sensors capable of detecting a wide range of gases, suited for consumer and commercial IoT applications, industrial safety systems, and environmental and air quality monitoring.

Interlink Electronics Inc holds a strong position within the sensing technologies and printed electronics industry. The company's competitive advantages include its leadership in printed electronics, pioneering FSR® technology, and expertise in materials science, printed electronics manufacturing, embedded electronics, and system integration. Interlink's multi-technology sensor fusion strategy and sensor fusion platform enable it to address performance gaps in conventional designs and provide enhanced durability, reliability, and environmental resistance compared to legacy mechanical or capacitive-only systems. The company's strategic acquisitions have broadened its capabilities and market reach, allowing it to compete effectively against legacy switch technologies and commoditized capacitive sensors in the force/touch sensing market. In the gas sensing market, Interlink competes by offering smaller, lower-cost, customizable electrochemical sensors combined with advanced calibration and compensation techniques.

Interlink's customer base is widely dispersed geographically and includes many of the world's leading electronics companies, large multinational organizations, start-ups, design houses, original design manufacturers, OEMs, and universities. The company supplies some of the world's largest consumer electronics manufacturers, luxury and mid-market car companies, familiar names in the medical and industrial equipment markets, research engineers and designers entering the IoT market, and companies of all different sizes in other markets. International sales have historically accounted for a significant percentage of Interlink's revenue, with sales to customers in China and Japan representing notable portions of the company's total revenue.
