Pressure-Sensitive Conductive Sheet force sensor (Velostat/Linqstat) size 10 x 5 cm

From the shop's description

This conductive pressure sensitive material (also known as "Velostat" or "Linqstat") is a good addition for your wearable/sensor hacking toolkit. It is pressure-sensitive, by squeezing, it will reduce the resistance. This make it good choice for making flexible sensors. It is also much less expensive than off-the-shelf pressure or bend sensors too. Each order comes with 30cm x 30cm piece. You may cut your sheet into many pieces and use each of them alone. Note You can use our conductive thread for force sensor and sewing the pressure-sensitive conductive thread Features Dimensions : 100mm x 50mm Thickness : 0.2mm Weight : 18.66g Temperature Limits : -45°C to 65°C (-50°F to 150°F) Heat Sealable : Yes Check this instructable for pressure sensor sheet tutorial
