Sensors: Stretchable Self-Powered Fiber-Based Strain Sensor (Adv. Funct. Mater. 12/2015).

On page 1798, J. Zhou and colleagues present two kinds of pretreated cotton threads that are entangled to form an double helixes‐structure generator. The generator is then coiled around a silicone fiber to form an active fiber‐based strain sensor which shows sensitive and stable performance and has the ability to detect human body motions. This indicates potential applications in future self‐powered healthy monitor systems by detecting the mechanical deformation of the human body and surrounding environment. [ABSTRACT FROM AUTHOR]
