1. A cardiopulmonary resuscitation (CPR) sensor comprising:
- a thin and substantially flat flexible substrate;
one or more sensor arrays disposed on the flexible substrate that measure one or more compression characteristics;
an output interface disposed on the flexible substrate;
a processor or an analog circuit disposed on the flexible substrate and connected to the one or more sensor arrays and the output interface; and
a power source disposed on the flexible substrate and connected to the one or more sensor arrays, the output interface, and the processor or the analog circuit.

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.
