This flexible tactile pressure sensor gives your project a compact 4 x 8 pressure matrix for mapping contact across a small surface. It integrates 32 independent sensing points in a 20 x 10mm active area, making it useful for robotic grippers, electronic skin, wearable electronics, human-machine interaction and research setups.
The thin-film FPC sensor is designed for tight spaces and curved contact areas, with adhesive backing for easier mounting. A compact adapter board handles the sensing interface, so you can read matrix pressure data over UART instead of building separate analogue acquisition circuitry for each point.
UART cascade support helps reduce wiring complexity in multi-sensor prototypes, and the module is suited to Arduino, ESP32 and Raspberry Pi ecosystems. The kit includes the adapter board, the 4×8 flexible array pressure sensor and a 30cm flexible silicone connection cable.

Jargon buster
Plain-language definitions for the technical terms used above.
- ESP32
- ESP32 is a family of microcontroller modules with built-in wireless features such as Bluetooth and WiFi. Knowing this product uses an ESP32-based module helps explain how it provides wireless serial communication and firmware update features.
- FPC
- FPC stands for flexible printed circuit, a flat flexible cable or connector style often used where space is tight. It matters because this breakout needs the correct pin count and pitch FPC cable to connect reliably to the display or high-speed interface.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
