Abstract: This invention comprises a stretchable electronic patch for monitoring impacts and other events. The stretchable, flexible electronic impact monitor patch includes geometric patterning of the substrate which enables stretching and flexing of the patch while leaving substrate regions at low strain for placement of electronic components, sensors and interconnects, maintaining electrical function during stretching and flexing. The stretchable, flexible, conformable patch enables wearability of the patch. In addition to monitoring impact events, other sensors may be incorporated for monitoring temperature, pressure, moisture, motion, location and other parameters. The patch may further possess an adhesive backing for adhering the patch to the head, the body or the object. The patch may take the form factor of a bandaid or bandage for comfortable wearing directly on the human body. The patch may also be coated to enhance comfort and also protect against moisture, water, and other environmental factors.
