Abstract
A method for determining a threshold voltage for a batch of sensing chips includes steps of: a) selecting at least three of micro-machined transceivers; b) conducting for each of the at least three of the micro-machined transceivers the following sub-steps of: b1) introducing a blank liquid into a micro-channel via an inlet port, b2) applying an alternate voltage to a micro-machined transmitter for a period of time, and b3) measuring an amplitude of an electric signal from a micro-machined receiver to obtain a maximum value and a minimum value; c) measuring a mid-value; and d) determining the threshold voltage. Also disclosed is a method for increasing sensitivity of the batch of sensing chips based on the threshold voltage.
