Ultrasonics slash cost of gas sensors

Ultrasonics slash cost of gas sensors:  A gas sensor using ultrasonic measurements is set to slash the cost of medical monitoring.

The new ultrasonic sensor uses patent-pending technology developed by TTP in Cambridge to precisely measure the speed of sound in a gas to determine its composition. While current infrared gas sensing devices for carbon dioxide can cost over £240 and paramagnetic systems for oxygen around £120, TTP believes that its new SonicSense devices will cost between £3 and £6 each in volume production. Potential medical applications include respiratory monitoring, anaesthesia and heart monitoring.
