Method of assembling artificial electronic skin

A method comprising:

• obtaining an artificial electronic skin assembly including:
• a first assembly including a plurality of transistors, a semiconductor layer, a plurality of active regions within the semiconductor layer, the active regions forming parts of the transistors, and a plurality of electrically isolated, first arrays of first electrically conductive nanostructures, each first array being electrically connected to one of the transistors;
• a second assembly including a flexible handle and a plurality of second electrically conductive nanostructures secured to and extending from the flexible handle, the plurality of the second nanostructures being electrically connected to a reference potential, the first assembly being mounted to the second assembly such that the first nanostructures of the first arrays and the second nanostructures are interdigitated and form variable resistors;
• exerting pressure on the flexible handle in the direction of the first assembly, thereby causing relative movement of the interdigitated first and second nanostructures and changing the electrical resistance of one or more of the variable resistors, and
• detecting the pressure exerted on the flexible handle based on the change in electrical resistance.
