Patent ID: 7510642

Claim:
A method for improving a reading resolution of a biosensor, comprising: providing a specimen on a chip of a biosensor, wherein the chip generates a peak voltage in response to a specific component of the specimen; selecting a voltage-time discharge curve corresponding to the peak voltage in accordance with a mapping table of peak voltage versus voltage-time discharge curve; using a voltage V 0 of a sampling time t 0 of the voltage-time discharge curve as a central voltage, and selecting a plurality of respective voltages whose sampling times are close to the sampling time t 0 , thereby obtaining an average voltage of the central voltage V 0 and the plurality of respective voltages to serve as an output voltage corresponding to the sampling time t 0 ; obtaining an average voltage corresponding to each sampling time of the voltage-time discharge curve before the time of discharge ending to serve as an output voltage of each sampling time based on the former step; converting the output voltage for each sampling time of the voltage-time discharge curve into a set of binary digital signals; and determining a reading of a concentration of the specific component in accordance with the sets of binary digital signals before the time of discharge ending.
