The Sensitive Side Of Carbon Nanotubes: Creating Powerful Pressure Sensors

Blocks of carbon nanotubes can be used to create effective and powerful pressure sensors, according to a new study. Taking advantage of the material's unique electrical and mechanical properties, researchers repeatedly squeezed a 3-millimeter nanotube block and discovered it was highly suitable for potential applications as a pressure sensor. No matter how many times or how hard they squeezed the block, it exhibited a constant, linear relationship between how much force was applied and electrical resistance.
