Textile-based monitoring system for biker

A wearable monitoring system for biker is presented, with textile-based clip type tension sensors on belt and pants to detect biker's breath and steps, respectively, and an accelerometer, together with clip type sensors to detect falling down and other biking conditions. The clip type sensors are fully made of textile, so they are washable, durable, low cost, easily installed on ordinary clothing, and comfortable. The clip sensors and the accelerometer are able to output signals to a microcontroller to derive breath rate, step counts, posture, and flatness of road. The microcontroller will then transmit the information through Bluetooth interface to a PDA for further analyzing and send messages through mobile telephone when necessary. The system provides information about biker's physical condition, movement of bicycle, and road condition, which are important for both health and safety of modern citizen.
