Superfast Mobile Devices
Scientists working in GE labs have developed tiny electrical switches thinner than a human hair that can transmit kilowatts of power. They are called micro-electro-mechanical systems, or MEMS.
The technology’s DNA is built around industrial applications, and MEMS could help reduce waste heat and power consumption in medical devices, aviation systems and other GE products.
MEMS are the Cinderellas of the electronic world. They do a lot of hard work, but get very little recognition.
The tiny chips, their full name is micro-electro-mechanical systems, can sense mechanical motion and convert that motion into electrical signals. “Just about everybody has them in their cellphones,” says Nicholas Yost, electronics technician at GE Global Research. These sensors, accelerometers and gyroscopes can detect the right screen orientation in smartphones, sense motion in Wii controllers, and even deploy airbags in cars.
