Publication number: 20100198039Abstract: The invention relates to wireless biotelemetry of low level bioelectric and biosensor signals by means of directly modulating the backscatter of a resonant circuit. Low level electrical analog or digital signals are directly applied to a resonant circuit containing a voltage-variable capacitor such as a varactor diode, that proportionally shifts the resonant frequency and so amplitude of radiofrequency backscatter in a way that represents analog bioelectric or biosensor waveform data. By strongly driving the resonant circuit with a radiofrequency source, a voltage variable capacitance can be caused to amplify the bio-signal level by a parametric process and so provide sufficient sensitivity to telemeter for low millivolt and microvolt level signals without additional amplification. A feature of the device is its simplicity and that it accomplishes both modulation and preamplification of low level sensor signals by the same variable capacitance circuit which reduces the device size and power consumption.Type: ApplicationFiled: May 2, 2008Publication date: August 5, 2010Applicant: Arizona Board of Regents For and On Behalf of Arizona State UniversityInventor: Bruce C.
