Description

Fundamental new approach for developing electrical devices that need no external power source or electrical connections.

NASA’s Langley Research Center researchers have developed a wireless, connection-free, open circuit technology that can be used for developing electrical devices such as sensors that need no physical contact with the properties being measured. At the core of the technology is the SansEC [Sans Electrical Connections] circuit, which is damage resilient and environmentally friendly to manufacture and use. The technology uses a NASA award-winning magnetic field response measurement acquisition device to provide power to the device and, in the case of a sensor application, to acquire physical property measurements from them. This fundamental new approach using open circuits enables applications such as sensors for axial load force, linear displacement, rotation, strain, pressure, torque, and motion sensing, as well as unique designs such as for a wireless keypad or wireless rotational dial, or for energy storage.
