Traditional self-defense tools either offer limited stopping power (pepper spray) or are too lethal and impractical for everyday carry (firearms). In close-range situations, especially if attacked from behind, reaching for a handheld taser is often too slow to be effective. I needed a wearable defense mechanism that is always “in hand” and instantly deployable.
I designed a compact, glove-integrated high-voltage system using a 9V battery feeding a voltage-multiplying circuit sealed inside an epoxy-filled casing for insulation and safety. The glove routes the output to electrodes between the fingers, generating ~80,000-volt arcs when activated. A built-in pressure switch ensures the circuit only closes when intentionally pressed, reducing accidental discharge risk.
Provided a fast, wearable way to defend yourself without needing to reach for a handheld device
Delivered enough stopping power to deter an attacker while staying nonlethal
Activation felt intuitive and immediate because it’s literally built into your hand
Verified non-lethal output the hard way (I accidentally shocked myself during early testing)
