Project Description:
The device is powered by piezoelectric energy generated through walking or other movement, minimizing the need for frequent charging and increasing reliability in critical moments. When activated by a vigorous stomp, the alarm emits a distinct sound that reaches up to 100 decibels—about the volume of a car horn or your average rock concert. The device attaches to the top of a shoe using two lace holes, with a thin piezo pad resting inside. A strong stomp or kick activates a “Listening” mode, indicated by a haptic vibration, turning the safety off to arm the device. If a second stomp occurs within 10 seconds, a 104-decibel alarm is triggered; otherwise, the device resets automatically.
