Abstract: A mobile touchable system for user fitness and health monitoring is presented. The system is designed in one form as a mobile phone case and in another form as integrated in a mobile phone. It encompasses a series of measurement devices, including, but not limited to, arrays of electrodes for bio-impedance analysis, impedance tomography, and electrocardiographs, near-infrared spectroscopy for glucose level measurement, and heart rate monitoring. The touchable system performs incidental measurement in the background each time the user holds the mobile phone and hence enables long term health monitoring without user intervention. The touchable monitoring system further performs targeted spot measurements by following defined procedures. Spot measurement is enhanced through an extension measurement cable. Furthermore, an extension strap along with the mobile touchable system provides detailed activity tracking.
