1. A health data collecting system comprising:

  • a wireless chip formed over a flexible substrate, the wireless chip including;

    a sensor circuit for obtaining biological information data;

    a modulating circuit; and

    a logic circuit;

    an antenna circuit for transmitting the biological information data;

    an interrogator which transmits electromagnetic waves to the wireless chip; and

    a data system evaluating the biological information data from the wireless chip,wherein the sensor circuit, the modulating circuit, and the logic circuit each comprises a thin film transistor,wherein the thin film transistor is formed over a protective film which is formed over the flexible substrate,wherein an interlayer film and a wiring that is arranged to be connected to an antenna are formed over the thin film transistor, andwherein a thickness of the protective film and a thickness of the interlayer film are arranged to be equal or substantially equal to each other.
