Abstract:
An apparatus including first and second electrodes separated by an electrolyte, at least one of the first and second electrodes including an actuating substrate configured to undergo reversible deformation during actuation, wherein reversible deformation of the actuating substrate causes a decrease in the internal resistance of the apparatus.
Abstract:
A battery cell (2) comprising: an anode (4) configured to operate as a source of cations during discharge of the battery cell; a cathode (8); and an electrolyte (6) configured to transport the cations from the anode (4) to the cathode (8) during discharge of the battery cell, wherein the cathode (8) comprises a material (20) that is configured to enable the reversible insertion of transported cations during discharge of the battery cell and to have optical properties that are dependent upon cation insertion and that is viewable by a user (12) and the material comprises Vanadium Oxide, wherein the optical properties of the material comprise any one of the following: a change of polarization, transmission, reflection and brightness of the material, and wherein the cathode comprises a translucent or transparent flexible substrate that enables a user (12), by visual inspection (14) through the substrate, to identify a change in the optical properties of the material.
Abstract:
In one or more embodiments described herein, there is provided an apparatus for a user interface, the user interface including a user interface surface, the user interface surface including at least part of a self cleaning composition, the composition being configured to draw away at least one dermatological contaminant from one or more contaminated regions of the user interface surface to thereby provide a self-cleaning user interface surface.
