Subtle vibrations, such as sound and ambient noises, are common mechanical waves that can transmit energy and signals for modern technologies such as robotics and health management devices. However, soft electronics cannot accurately distinguish ultrasmall vibrations owing to their extremely small pressure, complex vibration waveforms, and high noise susceptibility. This study successfully recognizes...
A copolymerization strategy is developed to utilize porphyrin as a complementary light‐harvesting unit (LHU) in D–A polymers. For polymer solar cells (PSCs), the presence of LHUs increases the short‐circuit current density (Jsc) without sacrificing the open‐circuit voltage (Voc) and fill factor (FF). Up to 8.0% power conversion efficiency (PCE) is delivered by PPor‐2:PC71BM single‐junction PSCs. A...
