Velostat Pressure Sensitive Conductive Sheet

What makes Velostat, also known as Linqstat, so unique is it's pressure sensitivity. When pressure is applied on the material, the resistance drops! Place some Velostat between 2 pieces of conductive thread, 2 conductive swatches or 2 sheets of conductive fabric to make your own, pressure sensing circuits. When someone steps on, presses or squeezes, the resistance will decrease.

Features:

• Resistance decreases as pressure increases
• Useful for making DIY force sensors that can measure heavy things (such as placing on the soles of the feet to measure steps)
• Dimensions: Approximately 1 square foot (12" x 12")
• Color: Opaque Black (as shown)
• Thickness: 4 Mil (0.1mm)
• Great for making flexible sensors in fabrics too! (such as detecting when a stuffed animal is hugged)
• Operating Temperature: -45C to 65C (-50F to 150F)
• Volume Resistivity: < 500 ohm cm
• Surface Resistivity: < 31000 ohm / sq.cm
• Heat Sealable
