Abstract: A tactile sensor, computer readable medium, methods of using and manufacturing the tactile sensor, and methods and apparatuses for processing the information generated by the tactile sensor. The tactile sensor includes a planar optical waveguide comprised of a flexible and transparent layer, a light configured to direct light into the optical waveguide; a light sensor or an imager facing the optical waveguide and configured to generate signals from light scattered out of the optical waveguide; and a controller which may be configured to generate an image of the object and characteristics of the object. The waveguide may be configured so that some of the light directed into the optical waveguide is scattered out of the waveguide if the waveguide is deformed by being pressed against the object. A finite element and a neural network are used to estimate mechanical characteristics of the objects.

Abstract: A structural color changeable material includes a strain body and surface plasmon generating particles. In the strain body, a strain is produced by an external pressure or an internal change. The surface plasmon generating particles generate surface plasmon and are contained in the strain body. The surface plasmon is generated by an incident light with a wavelength of 2400 nm or less. A mean particle size of the surface plasmon generating particles is equal to or less than the wavelength of the incident light. The surface plasmon generating particles are periodically arranged parallel to an in-plane direction of a reflection surface of the incident light.

Abstract: In an example, a pressure indicator film includes a first polymeric film material and a second polymeric film material that satisfy a threshold thermal degradation temperature. The pressure indicator film includes microcapsules on a surface of the first polymeric film material and a developer material on a surface of the second polymeric film material. The microcapsules are formed from a polymeric shell material that satisfies the threshold thermal degradation temperature. The microcapsules encapsulate a payload that includes a pH indicator and a solvent having a boiling point that is greater than the threshold thermal degradation temperature.

Abstract: The development of a stress-responsive colorimetric film that can memorize the stress it has experienced is disclosed. The system can use the plasmonic shift associated with the disassembly of one-dimensional plasmonic nanoparticle chains driven by the plastic deformation of the surrounding polymer matrix. By modifying the plasticity of the polymer, the plasmonic shift and colorimetric change can respond to a large range of stresses. The pressure indicating film can be used to capture and record the pressure distribution and magnitude between two contacting or impacting surfaces by outputting color information.
