In article number 2003381, Hendrik Schlicke, Tobias Vossmeyer, and co‐workers present a pressure sensor based on a free‐standing gold nanoparticle membrane acting as a diaphragm and resistive transducer. The elastic membrane features strain‐sensitive conductivity that is governed by tunneling through the interparticle gaps. While measuring the resistance of the bulged membrane, the topography is scanned using an atomic force microscope to explore its electromechanical properties.
