Description

<jats:title>Abstract</jats:title><jats:p>Electrochemically up‐regulated surface‐enhanced Raman spectroscopy (E‐SERS) effectively increases Raman signal intensities. However, the instrumental requirements and the conventional measurement conditions in an electrolyte cell have hampered its application in fast and on‐site detection. To circumvent the inconveniences of E‐SERS, we propose a self‐energizing substrate that provides electrical potential by converting film deformation from a finger press into stored electrical energy. The substrate combines an energy conversion film and a SERS‐active Ag nanowire layer. A composite film prepared from a piezoelectric polymer matrix and surface‐engineered rGO that simultaneously presents high permittivity and low dielectric loss is the key component herein. Using our substrate, increased E‐SERS signals up to 10 times from a variety of molecules were obtained in the open air. Various tests on real‐life sample surfaces demonstrated the potentials of the substrate in fast on‐site detection.</jats:p>
