A*STAR Institute of Microelectronics (IME) has partnered with a leading automotive MNC to develop a high accuracy temperature sensor integrated circuit block for automotive and industrial applications.

The temperature sensor will be part of a tyre pressure monitoring system (TPMS) which maintains the correct tyre pressure for comfortable driving, fuel efficiency, longer tyre-life and higher safety for the driver.

"The employment of a TPMS can reduce road accidents, fuel consumption and CO2 emissions," the research agency said.

The accuracy of TPMS is affected by the change of temperature. Current temperature sensor accuracy is on the order of ±3�C, which limits the performance and safety feature of TPMS.

Using 0.13µm CMOS technology, IME and the industry partner will work together on the design of a new temperature sensor IC for TPMS to dramatically improve the accuracy down to ±0.5°C. With the substantial improvement in temperature sensor accuracy, the TPMS will have greater capacity to pre-empt and react to enhance safety for the driver.

Professor Dim-Lee Kwong, executive director, IME, said, "Partnering with an industry leader to bring automotive IC design capabilities to Singapore adds immense value to the local semiconductor ecosystem."
