Puntech
AI-powered VR boxing training partner with flexible impact sensors.
Motivation
Boxing training has always relied on a coach standing across from you, a heavy bag, or a partner — none of which are available 24/7, and none of which can quantify what just happened in the last three seconds. Puntech reimagines the heavy bag as a sensor-instrumented, voice-interactive partner that can spar with you, count your shots, and adapt the workout in real time.
How it works
Flexible piezoelectric and triboelectric sensors are embedded across the impact surface of a VR-paired training pad, capturing the location, force, and timing of every strike. The signals stream to an on-device AI agent that classifies punch type (jab / cross / hook / uppercut), evaluates technique, and responds with adaptive verbal coaching through a conversational voice interface — turning a passive bag into an active sparring partner.
