    摘要: A micro mechanical backscatter sensor includes a receiver for receiving a modulated electromagnetic signal, a capacitive element operatively connected to the receiver, the capacitive element being arranged such that a voltage is generated across the capacitor in response to the frequency of the received signal, and a resonator operatively connected to the capacitive element such that electrostatic forces that are induced by the voltage generated cause the resonator to vibrate at a resonance frequency, the resonator being arranged such that an applied external force alters the resonance frequency of vibration. The sensor further includes a demodulator for demodulating the received signal, a modulator for modulating a carrier signal of the received signal by mixing the carrier signal with the resonance frequency of the resonator to produce a modulated electromagnetic transmission signal, and a transmitter, operatively connected to the capacitive element and arranged to transmit the modulated transmission signal.
