Systems are described for monitoring environmental conditions around extremities to aid in preventing damage associated with physical impact. A device embodiment includes, but is not limited to, a deformable substrate configured to conform to a skin surface of a body portion; a sensor assembly coupled to the deformable substrate, the sensor assembly including a proximity sensor configured to generate a sense signal associated with a proximity of an environmental object relative to the body portion; circuitry operably coupled to the sensor assembly and configured to receive the sense signal associated with the proximity of an environmental object relative to the body portion; and a reporting device operably coupled to the circuitry and configured to generate a communication signal associated with one or more of the environmental object or the proximity of the environmental object relative to the body portion responsive to instruction by the circuitry.
