Claim 9:
10. A method for detecting potential power failure, for use in an electric carrier, wherein the electric carrier comprises a piezoresistive sensor, a battery interface, and a power-management unit (PMU), wherein the battery interface is connected to an on-board battery and receives power from the on-board battery, the method comprising:
utilizing a piezoresistive strain gage disposed in the contact area between the battery interface and the on-board battery to detect a pressure value of the contact area;
utilizing the piezoresistive sensor to receive the pressure value detected by the piezoresistive strain gage, and to convert the pressure value into a resistance value;
utilizing the piezoresistive sensor to generate a resistance-value-determination signal; and
utilizing the power-management unit to provide power to the motor in response to the resistance-value-determination signal being determined by the power-management unit as within a safe resistance value range.
