Sensing a change in motion proximate to an arbitrarily-shaped surface via a single sensing element (e.g., a pressure sensor, an accelerometer) disposed on a flexible substrate having a sufficient mechanical coupling to the arbitrarily-shaped surface. The change in motion may include at least one of an acceleration, an orientation, a vibration shock and a falling process. In one example, the flexible substrate substantially conforms to the arbitrarily-shaped surface so as to facilitate intimate proximity to the arbitrarily-shaped surface. In another example, a coupling mechanism may mechanically couple the sensing element to the arbitrarily-shaped surface. One or more LEDs coupled to the sensing element may provide a visual cue representing impact or trauma to the surface based on different colors respectively corresponding to a degree of the impact or trauma. |
