Abstract
A sensor system (30) has a sensor module (10) and a receiver module (45). The sensor module (10) functions as a wireless data collection device and has a flexible thin sheet of silicon (60, 65, 70) comprising circuitry (71, 72, 73), a flexible power source (105), and a flexible support substrate (55). The silicon, power source, and flexible support substrate are integrated as layers of the sensor module (10). The layers are placed together in the form of an adhesive bandage (10). A plurality of electrodes (80) are connected to the sensor module (10) and protrude from the flexible substrate (55) for contacting the skin of a subject body (20). The receiver module (45) includes one of an RF receiver with a wireless port for continuously receiving data (40), or a physical I/O port (87) to which the sensor module (10) can be physically connected for downloading stored data from the sensor module (10).
