The need

Three markets. One unmet need.

Methane, refrigerants and indoor air quality all demand continuous, distributed monitoring. Today's gas sensors are too big, too power-hungry and too expensive to deploy everywhere.

Oil & Gas · Methane$3.8B

Methane detection & monitoring

DRIVER · FINANCIAL

Operators cut product loss, emissions cost and ESG risk.

HVAC/R · Refrigerants$1.5B

Refrigerant leak detection

DRIVER · REGULATORY

UL 60335-2-40 requires a detector in A2L equipment since January 2025.

Air Quality$5.8B

Air-quality monitoring systems

DRIVER · CONSUMER PULL

Firms market healthy spaces; consumers buy for health.

Our solution

A CMOS resonator turns gas into data.

A chemically selective receptor sits on a GHz piezoelectric resonator, built directly on a CMOS chip. When gas adsorbs, the added mass shifts the resonant frequency, and on-chip electronics turn that shift into a digital reading.
