Velostat 10 x 20cm

Velostat is a flexible, pressure-sensitive material perfect for creating custom sensors in wearable tech, soft robotics, and interactive art. Lightweight and durable, it changes resistance when pressed, bent, or stretched — making it ideal for DIY projects that need touch, force, or bend detection.

When compressed, its resistance drops — perfect for creating soft pressure pads, touch sensors, and DIY electronics projects.

Use it to build your own force sensors, squeeze switches, flex sensors, or experimental interfaces. Whether you’re prototyping a new wearable or adding interactivity to a creative build, Velostat gives you reliable, repeatable results without bulky hardware.

This 10 cm × 20 cm sheet (0.1 mm thick) handles temperatures from –45°C to 65°C and features heat-sealable edges. If it arrives creased, just flatten it under a book.

With low volume resistivity (<500 ohm·cm) and surface resistivity (<31,000 ohms/sq.cm), it’s ready for your next maker experiment.

Works great alongside our Pressure Pack & Servo kit for a complete pressure-sensing project.

How It Works

Velostat is a carbon-impregnated polymer that changes electrical resistance when pressure is applied. More pressure → lower resistance. This makes it perfect for DIY force, touch, and bend sensors.

Common Project Ideas

• Force-sensing buttons
• Soft robotics pressure pads
• Wearable squeeze sensors
• Flex sensors for gloves or joints
• Interactive art installations
• Smart textiles
• Musical interfaces

How to Use

• Cut with scissors
• Layer between conductive fabric or copper tape
• Connect to analog input pins
• Works best with a voltage divider

Specifications

• Size: 10 cm × 20 cm
• Thickness: ~0.1 mm

Note: Velostat has a reported limited lifespan under repeated heavy compression or creasing. I haven’t personally run into these issues, but worth keeping in mind for high-cycle applications.
