Title:
FERROELECTRIC COMPOSITE MATERIAL-BASED ARTIFICIAL ELECTRONIC SKIN
Document Type and Number:
WIPO Patent Application WO/2017/043695
Kind Code:
A1
Abstract:
An artificial electronic skin according to the present invention comprises: a lower electrode; a first layer laminated on the lower electrode; a first micro dome formed on the first layer in a semispherical shape so as to stand upright upwards; a second layer laminated on the first layer; a second micro dome formed on the lower portion of the second layer, which lies opposite the first layer, in a semispherical shape to be able to engage with the first micro dome; an upper electrode laminated on the upper end surface of the second layer; and a pattern layer laminated on the upper end surface of the upper electrode so as to receive an external pressure applied thereto. The artificial electronic skin according to the present invention is advantageous in that a dynamic pressure, a static pressure, and a temperature can be sensed and distinguished by a single element, using different signals.
