A major challenge accompanying the booming next-generation soft electronics is providing correspondingly soft and sustainable power sources for driving such devices. Here, we report stretchable triboelectric nanogenerators (TENG) with dual working modes based on the soft hydrogel–elastomer hybrid as energy skins for harvesting biomechanical energies. The tough interfacial bonding between the hydrophilic hydrogel and hydrophobic elastomer, achieved by the interface modification, ensures the stable mechanical and electrical performances of the TENGs. Furthermore, the dehydration of this toughly bonded hydrogel-elastomer hybrid is significantly inhibited (the average dehydration decreases by over 73%). With PDMS as the electrification layer and hydrogel as the electrode, a stretchable, transparent (90% transmittance), and ultrathin (380 μm) single-electrode TENG was fabricated to conformally attach on human skin and deform as the body moves. The two-electrode mode TENG is capable of harvesting energy from arbitrary human motions (press, stretch, bend, and twist) to drive the self-powered electronics. This work provides a feasible technology to design soft power sources, which could potentially solve the energy issues of soft electronics.

摩擦电纳米管为基础的柔软能量收集皮肤，可通过牢固键合的弹性体/水凝胶杂化剂实现

蓬勃发展的下一代软电子产品所面临的主要挑战是提供相应的软且可持续的电源来驱动此类设备。在这里，我们报告了基于软水凝胶-弹性体杂化体的双重工作模式的可拉伸摩擦电纳米发电机（TENG），它是收集生物机械能的能量皮肤。通过界面改性，亲水性水凝胶和疏水性弹性体之间的牢固的界面结合确保了TENG的稳定的机械和电气性能。此外，这种坚硬结合的水凝胶-弹性体杂化物的脱水作用得到了显着抑制（平均脱水作用降低了73％以上）。以PDMS为带电层，以水凝胶为电极，可拉伸，透明（透射率90％），并制造了超薄（380μm）单电极TENG，以保形地附着在人体皮肤上并随着人体移动而变形。双电极模式TENG能够从任意人体运动（按压，拉伸，弯曲和扭曲）中收集能量，以驱动自供电电子设备。这项工作为设计软电源提供了一种可行的技术，可以潜在地解决软电子设备的能源问题。
