Velostat Pressure-Sensitive Sheet – 280×280mm

The Pressure-Sensitive Conductive Sheet (Velostat) is a flexible carbon-impregnated polymer material designed for creating custom pressure and touch sensors. It changes resistance when mechanical force is applied, enabling simple analog sensing in wearable and embedded systems. With a thickness of 0.1 mm and volume resistivity below 500 ohm·cm, it provides consistent electrical behavior across its surface. The sheet is heat sealable and operates within -45°C to 65°C, making it suitable for prototyping, interactive surfaces, and low-cost sensor development.
