DecoLive Jacket with Battery-Free Dynamic Graphics

We present the design and prototype of the DecoLive Jacket, a dynamic clothing that allows its wearer to switch between opened and closed states of flower patterns as subtle indication of availability for social interactions. The Jacket embodies two electrochromic (EC) displays and NFC-based wireless energy harvesting components, enabling battery-free operation. The wearer controls the garment’s patterning by placing a smartphone in one of the two pockets of the jacket, activating either the open or closed flower visualization, and expressing a subtle message about their willingness to interact with others. Our implementation demonstrates the potential for battery-free EC displays on aesthetic wearables to enable dynamic control of the non-verbal messages communicated by clothing.
