Abstract
A source signal is converted into a time-variant temperature field with transduction into mechanical motion. In one embodiment, the conversion of a source signal into the time-variant temperature field is provided by utilizing a micro-fabricated fast response, bolometer-type radio frequency power meter. A resonant-type micromechanical thermal actuator may be utilized for temperature read-out and demodulation.

A method of signal processing for extracting base-band information from a broadcast signal, the method comprising:
- converting a radio frequency signal into heat;
- and
- measuring temperature changes representative of the radio frequency signal.
A method of signal processing for extracting base-band information from an amplitude modulated broadcast signal, the method comprising:
- converting the amplitude modulated broadcast signal into heat using a micro-fabricated resistive heater having a thermal inertia small enough to follow the modulation;
- and
- measuring temperature changes in the micro-fabricated resistive heater.
A method comprising:
- converting a broadcast signal into temperature oscillations;
- and
- converting the temperature oscillations into mechanical motion representative of the broadcast signal.
