Taiwan unveils technique to combine sensors on a chip

Taipei, March 24 (CNA) Taiwanese researchers have developed a technique to integrate different sensors on a single chip, making it smaller and more energy-efficient than the chips currently used in wearable devices. The National Applied Research Laboratories unveiled the technique Tuesday, saying it allows for the inclusion of three major categories of sensors on one chip. One type of sensors registers temperature, humidity, pressure and other weather data, while another measures the user's heartbeat, blood pressure, blood sugar, and the third type records the user's speed of movement and other physical factors. Currently, the three different kinds of sensors are run by independent chips and the data is integrated with chips designed for calculations and communications in wearable devices. The new technology will help save energy and costs for makers of smart phones and wearables by packing various sensors and other functions into one system-on-chip, that is half the size of a rice grain, the institute said. The use of sensor chips has been increasing with the growing popularity of the Internet of Things and wearable devices. French market researcher Yole D憝eloppement (Yole) has predicted that the annual production value of sensor chips will reach US$24 billion by 2019. Taiwan manufactures 60 percent of the chips in the world and designs 12 percent of them, but designs less than 1 percent of sensor chips globally. (By Milly Lin and Scully Hsiao)
