In this paper we present a smart handheld system for point of care biosensors. The system consists of a novel multi-path potentiostat module which performs electrochemical measurements on disposable test strip. The strip provides a port for applying bio-sample such as blood or urine. The analyte port on the disposable strip is designed with 3 sets of 3 electrodes (Working, Reference and Counter electrodes) screen printed on a Polyethylene Terephthlate (PET) substrate. The system provides the unique capability of performing Cyclic Voltametry and Chrono Amperometry measurements in three parallel paths, facilitating simultaneous measurement of three bio-analytes. The system is very generic and flexible, with user defined inputs for voltage, sweep rate and time through 5 inch capacitive touch screen. The experimental results can be stored on micro SD card and the data is accessible with USB or Bluetooth interface.
