World’s Smallest Reed Switch Makes Technology Easier to Swallow

By Charles Murray – Known as the RedRock MEMS (microelectromechanical systems) switch, the new product could serve in such applications because it measures just 1 mm x 1 mm square. In contrast, conventional reed switches typically measure at least 4 mm to 5 mm long, due to technical limitations in the manufacturing process.

The technology may be best suited to a device known as an ingestible endoscope, which, after being swallowed, uses video cameras to take pictures of a person’s gastrointestinal tract. Today, such pill-shaped endoscopes measure an unappetizing one-inch long by almost half an inch wide, making them difficult to swallow. A MEMS-based reed switch would significantly reduce the size of such devices. more>
