1. A method for improving a reading resolution of a biosensor, comprising:

  • providing a specimen on a chip of a biosensor, said chip generating a time-varying response current in response to a specific component of said specimen, so that a voltage-time discharge curve is established in response to a specific component of said specimen;

    using a voltage V0 of a sampling time t0 of said voltage-time discharge curve as a central voltage, and selecting a plurality of respective voltages whose sampling times close to said sampling time t0, obtaining an average voltage of said central voltage V0 and said respective voltages to serve as an output voltage corresponding to said sampling time t0;

    obtaining an average voltage corresponding to each said sampling time of said voltage-time discharge curve before the time of discharge ending to serve as an output voltage of each said sampling time based on the former step;

    converting said output voltage of each said sampling time of said voltage-time discharge curve to a set of binary digital signals; and

    determining a reading of a concentration of said specific component in accordance with the sets of binary digital signals before the time of discharge ending.
