Abstract Wearable flexible electronics (WFE) have great potential in health management and personalized medicine; however, their rapid development has led to a sharp increase electronic waste, leading environmental risks. Although previous studies proposed the use of degradable polymers, such WFE is disposable. Therefore, design recyclable promising, but relevant works been limited. Herein, vitrimer‐like polyurethane elastomer containing dynamic ureidopyrimidinone quadruple hydrogen bonding units (PU‐UPy) developed as substrate for sustainable WFE. The PU‐UPy tough with tensile strength 24.4 MPa, maximum strain 2950%, toughness 228 MJ m − 3 , satisfying mechanical requirements Moreover, thermally‐induced nature bonds donated by UPy makes via both solid solvent reprocessing. By creating microstructures shape reconfiguration, electrode layers are assembled into pressure‐sensing WFE, enabling motion monitoring Morse code recognition. Furthermore, can be fully recycled facile reprocessing; recycling reassembly could repeatable, still maintains good performance. Overall, this work provides inspiration from polymers.
