ITRI’s sensing chip, at 0.75 cubic nanometers, is only one fortieth the size of a rice grain. The small gas sensing chip can be integrated inside smart phones, watches and other wearable devices. The manufacturing of the sensing chip adopts the MEMS process, which can effectively reduce power consumption and increase production capacity. Measurement System Setup Multi-Gas Testing Chamber

It is not an unattainable technology for smart phones and watches to measure alcohol concentration via your breath! ITRI has launched its wearable intoxication-sensing watch. It is equipped with a built-in 0.75 mm3 (1.5 x 1.25 x 0.4 mm3) low power consumption sensing chip developed by the MEMS (microelectromechanical systems) technique. One fortieth the size of a rice grain, the chip can be directly integrated inside smart phones, watches and other wearable devices, eliminating the need to carry other testing gadgets for measuring the alcohol concentration via your breath. This device is expected to reduce the number of traffic accidents caused by drunk driving because people can check their intoxication level by just breathing onto their smart phone or watch.

The measuring range of ITRI’s wearable intoxication-sensing watch is 20-400 ppm. It has been designed with green, yellow and red indicator lights in accordance with domestic traffic regulations. The green light indicates a value on the breathalyzer of 0.15 mg/L or lower for safe driving. The yellow one represents the value of the statutory drunk driving limit (from 0.15 mg/L to 0.55 mg/L); driving, in this case, is not allowed. When the value is higher than 0.55 mg/L, the red light will go on, indicating that driving would be dangerous and shall be prohibited.

The manufacturing of its sensing element adopts the MEMS process, which can effectively reduce power consumption and increase production capacity. This technique can also be used to develop sensing elements in various applications: carbon monoxide for gas leakage, sulfur dioxide and nitrogen oxides for air pollution, and hydrogen sulfide for bad breath.
