Mild concussions occur frequently and may come with long-term cognitive, affective, physical sequelae. However, the diagnosis of mild lacks objective assessment portable monitoring techniques. Here, we propose a multiangle self-powered sensor array for real-time head impact to further assist in clinical analysis prevention concussions. The uses triboelectric nanogenerator technology, which converts force from multiple directions into electrical signals. With an average sensitivity 0.214 volts per kilopascal, response time 30 milliseconds, minimum resolution 1.415 kilopascals, sensors exhibit excellent sensing capability over range 0 200 kilopascals. Furthermore, enables reconstructed mapping injury grade via prewarning system. By gathering standardized data, expect build big data platform that will permit in-depth research direct indirect effects between impacts future.
