Interlink Electronics, Inc Announces $175,000 SBIR R&D Award From NOAA for Development of Advanced Wildfire Smoke Sensors

INTERLINK ELECTRONICS, INC. ANNOUNCES $175,000 SBIR R&D AWARD FROM NOAA FOR DEVELOPMENT OF ADVANCED WILDFIRE SMOKE SENSORS Recognizes Company’s leading posi3on in gas sensor research and commercializa3on September 6, 2023, 6:00 AM PDT IRVINE, CA – (Business Wire) - Interlink Electronics, Inc.

(NASDAQ: LINK), a world-leading provider of sensors and printed electronic soluGons that support a wide range of applicaGons, including Human- Machine Interface (“HMI”) devices and IoT soluGons, is pleased to announce that its Gas and Environmental SoluGons division has received a $175,000 SBIR award from NOAA for development of low- cost, low-power sensor nodes for monitoring air quality impacted by wildfire smoke.

As a result of climate change, the number and severity of wildfires have been increasing substanGally, as exemplified by the recent tragic events in Maui. In addiGon to the loss of life of both residents and firefighters, the indirect effects of wildfires can impact human health even if people are living hundreds of miles away from the fire.

EsGmates of deaths a^ributable to wildfire smoke globally are 300,000 to 400,000, especially among elderly people, children and people with preexisGng respiratory condiGons. “The smoke from Canadian wildfires that has blanketed major ciGes in the US this summer has highlighted the serious and growing public health concerns arising from wildfires.

In addiGon to the parGculate ma^er that makes the smoke visible, smoke also contains CO, NO2, SO2 and O3, all harmful for human beings,” said Dr. Sreeni Rao, General Manager of the Gas and Environmental Sensors Division. “There is currently no exisGng compact low-cost electrochemical system containing sensors for outdoor monitoring of all four gases.

We are proposing a low-cost, low-power miniaturized and easily deployable sensor that will deliver data for air quality in unmonitored areas capable of improving currently exisGng models, increasing awareness and understanding the impact of low air quality.” “Development of these sensors will enable us to penetrate into a large user base for more real-Gme air quality data,” added Steven N.

Bronson, Interlink’s CEO and President. “This award conGnues our history of qualifying for SBIR grants, and we are also pleased to note that NOAA recognized the superior scienGfic and engineering backgrounds and talents of the Interlink team.” About Interlink Electronics, Inc.

Interlink Electronics is a world-leading provider of sensors and printed electronic soluGons that support a wide range of applicaGons, including Human-Machine Interface (“HMI”) devices and IoT soluGons, uGlizing our experGse in materials science, manufacturing, firmware and sogware to produce in-house system soluGons for custom specificaGons.

We have a proven track record of supplying mission-criGcal technological soluGons in diverse markets including medical devices, automoGve, gas detecGon and environmental quality monitoring, oil and gas and general industrial, and consumer electronics, providing standard and custom-designed sensors that provide the flexibility and funcGonality needed for today's sophisGcated applicaGons.

The Company’s products and soluGons currently focus on three main fields:

• For nearly 40 years, the Company has led the printed electronics industry in commercializing its patented Force Sensing Resistor® technology, which offers pressure and posiGon sensing and rugged capabiliGes in a very wide range of temperatures.

Our piezoelectric film sensors offer strain, bend and vibraGon sensing and can be used on curved surfaces, while our advanced matrix sensor soluGons offer mulGple touch capabiliGes.

We supply some of the world's top electronics manufacturers with intuiGve sensor and interface technologies for use in advanced applicaGons such as medical roboGcs and vehicle collision detecGon. • Our Gas and Environmental Sensors division has over 25 years of experience in culng-edge design and manufacture of electrochemical gas-sensing technology for industry, community, health and home.

We provide advanced sensor soluGons, precision sensing instruments, and custom engineering services for detecGng gases such as carbon monoxide, ozone, hydrogen, NOX gases and ammonia, for transdermal alcohol detecGon and for air quality monitoring.

Our innovaGve printed sensor design enables high-sensiGvity, low-power and cost-effecGve soluGons for broad adopGon in the rapidly growing IOT market. • Our Calman Technology subsidiary brings over 25 years of experience in the design and manufacture of membrane keypads, graphic overlays and industrial label products.

We offer IP- rated digital and hybrid printed devices featuring integrated backlighGng and shielding and printed electronics with advanced materials ink prinGng. Calman has customers in fields such as medical devices and defense technologies and gives the Company a base in Europe.

We serve our internaGonal customer base from our corporate headquarters in Irvine, California; our Global Product Development and Materials Science Center and distribuGon and logisGcs center in Camarillo, California; our advanced printed-electronics manufacturing faciliGes in Shenzhen, China, and Irvine, Scotland; and our proprietary gas-sensor producGon and product development facility in Newark, California.
