A sensing device is provided having sensing circuitry, connected to an input port and the output port, with a sensor having an impedance sensitive to a parameter of interest, one or more passive electrical components, and a variable capacitor. The sensing circuitry is triggered to generate an output signal for transmission from the output port, the output signal dependent on the parameter of interest sensed by the sensor and on an input power value, P.sub.in, of an input signal received at the input port being greater than a parametric threshold power value, P.sub.th. A sensing system includes the sensing device and a transmitting device to transmit the input signal to the sensing device at a frequency representative of the parameter of interest. A receiving device, which can be incorporated with or located remotely from the transmitting device, receives the output signal of the sensing device, which has a frequency that is half of the frequency of the input signal transmitted by the transmitting device.

A device for measuring the temperature of a lower extremity of a subject in need of such monitoring. The device is especially suited for monitoring the foot temperature of a subject with diabetes or another condition that could lead to lower blood circulation and temperature in the lower extremities of the subject. Methods of preventing complications from such diseases, disorders, syndromes, or conditions are provided. The past recorded temperatures of the subject may be stored for comparisons and trends analyses.
