Abstract

A wearable jacket includes a 2D-DST substrate shaped to cover a body of a subject person. The 2D-DST substrate includes a first conductive sheet, a second conductive sheet and a plurality of communication modules. The first and second conductive sheets are overlapped, and the first conductive sheet is located on the subject person side when in use. The plurality of communication modules are distributed between the first and second conductive sheets. At least one of the plurality of communication modules has a communicating system capable of communicating with an external device by receiving and/or transmitting a spatially propagating signal. One of the first and second conductive sheets on the external device side is formed with an area that allows the spatially propagating signal to pass through at a position corresponding to a location of a communication module having the communicating system.
