Smart clothes are clothes made of fibers or fabrics integrating electronic components and combining information technology, which can be used as signal transmission. Looking at the technological changes of functional clothing, the content of patents has shifted from functionality to intelligence, gradually narrowing the gap between technology and reality. The design of smart clothing requires multi-faceted considerations. Cross-industry integration and cross-domain integration are inevitable trends in the future. Taiwanese industries already have the advantageous technologies required for smart clothing, breaking through the existing operating framework of wearable devices and combining with different needs and usage scenarios. And integrating wireless transmission module and communication technology, using fabric as the carrier of signal transmission, can achieve new thinking of creating value and new opportunities for product development.
