Document Type and Number:
WIPO Patent Application WO/2016/060427
Kind Code:
A1
Abstract:
Provided is a technique related to a new sensor unit which is flexible in that the sensor unit can be installed in various locations such as inside of a structure with a large curvature, and which can stably measure multi-directional deformation and very efficiently and wirelessly measure deformation information, and thus provided is a technique of a sensor structure which can be universally utilized in various systems for measuring deformation information. The sensor unit using an electro-active polymer for the wireless transmission/reception of deformation information, according to a first embodiment of the present invention, comprises: a first sensor part formed from a fiber or film comprising a ferroelectric electro-active polymer material; a second sensor part configured to include the first sensor part therein, and formed from a matrix comprising a dielectric elastomer electro-active polymer material; and an electrode part provided to come into contact with the first sensor part or the second sensor part and, when external force is applied to the first sensor part or the second sensor part, transmits to the outside an electric signal generated by the first sensor part or the second sensor part.
