23_30i/2011Strain Sensors: Single MWNT-Glass Fiber as Strain Sensor and Switch (Adv. Mater. 30/2011)

Early detection of material damage can be achieved using a carbon nanotube concentrated interphase between a single glass fiber and polymer resin. Edith Mäder, Shanglin Gao, and co-workers report on page 3392 that by bridging across a micro-crack with the nanotube networks, an exceptional electromechanical switch is fabricated. The switch exhibits “on” and “off” states actuated by strain, temperature, and light.
