This paper constructed a plantar pressure sensing system based on Bluetooth communication of mobile phone with embedded Windows Mobile system. With the MCU (Microprocessor Control Unit) and Bluetooth module, the pressure sensor and the data acquisition circuit was designed and integrated, with software developed under Visual Studio 2008 environment. The real-time monitoring of human dynamic plantar pressure signal, and transferring, displaying and storing the recorded data on a mobile phone were achieved. This method offers an important measure to acquire human gait information via a pervasive and low cost way.
