Low-Cost Gas Sensor Relies On Sound Velocity

Low-Cost Gas Sensor Relies On Sound Velocity

Claiming to deliver accurate gas sensing at a fraction of the cost of existing methods, TTP’s ultrasonic sensor uses patent-pending technology to precisely measure the speed of sound in a gas to determine its composition. According to the company, current infrared gas sensing devices for carbon dioxide can cost over $400 and paramagnetic systems for oxygen around $200. TTP says its SonicSense devices will cost between $5 and $10 each in volume production. Potential medical applications include respiratory monitoring, capnography, anesthesia, and COPD monitoring.
