smart insole 3d model

A pair of smart foot insoles, shown from top view and angled 3/4 perspective. Each insole looks like a normal shoe insole with smooth curved shape. Inside the insole, there are three round pressure sensors (FSR) placed at: Heel area (back of the foot). Midfoot arch (center of the foot). Forefoot (ball of the foot, before the toes). The sensors are small, thin, and flat, embedded neatly inside the insole surface. A slim cable runs along the side of the insole, connecting all 3 sensors and tiny ESP32 chip module together. The cable leads to a tiny ESP32 chip module placed near the arch or heel edge of the insole, responsible for transmitting the data wirelessly. The overall design should look clean, compact, and wearable, keeping the natural shape of a shoe insole.
