摘要

The development of stretchable/soft electronics requires power sources that can match their stretchability. In this study, a highly stretchable, transparent, and environmentally stable triboelectric nanogenerator with ionic conductor electrodes (iTENG) is reported. The ion-conducting elastomer (ICE) electrode, together with a dielectric elastomer electrification layer, allows the ICE-iTENG to achieve a stretchability of 1036% and transmittance of 91.5%. Most importantly, the ICE is liquid solvent-free and thermally stable up to 335 degrees C, avoiding the dehydration-induced performance degradation of commonly used hydrogels. The ICE-iTENG shows no decrease in electrical output even after storing at 100 degrees C for 15 h. Biomechanical motion energies are demonstrated to be harvested by the ICE-iTENG for powering wearable electronics intermittently without extra power sources. An ICE-iTENG-based pressure sensor is also developed with sensitivity up to 2.87 kPa(-1). The stretchable ICE-iTENG overcomes the strain-induced performance degradation using percolated electrical conductors and liquid evaporation-induced degradation using ion-conducting hydrogels/ionogels, suggesting great promising applications in soft/stretchable electronics under a relatively wider temperature range.
