Analog Devices redesigns High-G MEMS to help detect concussions

Published:2012/5/27 19:57:00 Author:Ecco From:SeekIC

Here is a kind of new MEMS sensor which is small enough to be mounted inside an athlete’s helmet. It can be used to detect ports-related concussions early. It is reported that ports-related concussions have occured in the U.S. over 3.8 million each year. The new MEMS sensor give doctors enough time to protect patient from preventative concussion.

According to the American Association of Neurological Surgeons, using high-G sensors for early detection of concussions could drastically reduce injuries. The Centers for Disease Control and Prevention indicated that more than 75 percent of concussions go undiagnosed, eventually contributing to over 30 percent of head trauma deaths in the U.S.. Early detection also could cut medical bills and lost productivity, which is estimated to exceed $76 billion annually.

Analog Devices has already produced single-axis, high-G accelerometers which are used to detect concussions in IndyCar drivers. The company recently redesigned their high-G sensor into a single chip to make it to fit inside football and other sports helmets. The high-G MEMS accelerometer measures 3-by-3-by-1.45 mm, making it small enough to fit inside a helmet-mounted earpiece to measure head trauma. The ADXL377 draws only about 300 microAmps, making it suitable of battery operation.
