Abstract
A thermometer includes a body member and a tip member with a thermal contact surface secured to the body member. A thermal sensor mounted on the inside of the tip member is adapted for sensing a thermal contact surface and producing a temperature signal. A set of lead wires is coupled to the thermal sensor for transmission of the temperature signal. A display module is disposed in the body member. A processor is electrically connected to the set of lead wires to receive the temperature signal for display of a corresponding temperature reading. An electric generator having a motor with a rotary shaft is disposed in the body member. The motor is driven for generating electric energy when the rotary shaft is rotated. A capacitor is electrically connected to the electric generator for storing the electric energy generated by the electric generator and supplying the electric energy to the processor.
