Abstract
This demo presents the world's smallest wireless motion-sensing platform based on Bluetooth 4.0 Low Energy (BLE) Technology. It is merely 8×8 mm 2 in area but is complete with a user-programmable microcontroller and integrated RF, a digital triaxial accelerometer with programmable threshold detection, and a real-time clock and calendar chip, and a magnetic sensor/switch. This system has been used in a number of applications, including a proximity tag, a pedometer, an air mouse with gesture recognition, and a BLE-to-IR remote controller. © 2014 IEEE.
