Abstract
A nanosensor for detecting a force includes a metal layer, a flexible-material layer, and a photoluminescent material. The flexible-material layer is deposited on a top surface of the metal layer. The photoluminescent material is attached to, or at least partially embedded in the flexible-material layer and configured to emit first photoluminescence when optically excited at an excitation wavelength. The first photoluminescence has a first wavelength different from the excitation wavelength. The first intensity of the first photoluminescence changes with a distance between the photoluminescent material and the metal layer, where the distance changes in response to the force acting on the flexible-material layer.
