Abstract: The present invention provides a CPR sensor that includes a thin and substantially flat flexible substrate having one or more sensor arrays, a power source, an output interface and a processor or analog circuit, all of which are disposed on the substantially flat flexible substrate. The substrate can be any shape (e.g., rectangular, circular, a polygon, an irregular shape that is decorative) and made from a polymer, metal film or other suitable material. Note that the substrate can be rigid or semi-flexible instead of flexible. A protective layer may cover the sensor array, the power source, and the processor or analog circuit. Alternatively, a protective covering can be used to encapsulate the device. The one or more sensor arrays measure one or more of the following compressions characteristics: compression depth, compression force, compression frequency and compression acceleration.

Abstract: A device is disclosed for remote monitoring of breathing movements of a patient, comprising a sender transmitting a microwave signal toward the patient, a receiver arranged to receive a signal reflected by the patient, and a processor. The processor mixes the received signal with the transmitted signal and with a signal in quadrature with the transmitted signal to determine a breathing frequency of the patient. In some embodiments, two signals at different frequencies are emitted toward the patient and processed in order to compensate for breathing patterns that are not uniquely resolvable at a single frequency.
