With the rapid development of human–machine interfaces, artificial acoustic sensors play an important role in the hearing impaired. Here, an ultrathin eardrum‐like triboelectric acoustic sensor (ETAS) is presented consisting of silver‐coated nanofibers, whose thickness is only 40 µm. The sensitivity and frequency response range of the ETAS are closely related to the geometric parameters. The ETAS...
Sodium metal anode, featuring high capacity, low voltage and earth abundance, is desirable for building advanced sodium‐metal batteries. However, Na‐ion deposition typically leads to morphological instability and notorious chemical reactivity between sodium and common electrolytes still limit its practical application. In this study, a porous BN nanofibers modified sodium metal (BN/Na) electrode is...
Inorganic perovskites with special semiconducting properties and structures have attracted great attention and are regarded as next generation candidates for optoelectronic devices. Herein, using a physical vapor deposition process with a controlled excess of PbBr2, dual‐phase all‐inorganic perovskite composite CsPbBr3–CsPb2Br5 thin films are prepared as light‐harvesting layers and incorporated in...
c2D transition metal dichalcogenides (TMDCs)‐based heterostructures have been demonstrated to achieve superior light absorption and photovoltaic effects theoretically and experimentally, making them extremely attractive for realizing optoelectronic devices. In this work, a vertical multilayered n‐MoS2/n‐silicon homotype heterojunction is fabricated, which takes advantage of multilayered MoS2 grown...
