    摘要： An apparatus (201) comprises a light emitter (202) and a photodetector (203) formed on a single fluid-permeable substrate (206) such that the photodetector (203) is able to detect light emitted by the light emitter (202) after interaction of the light with a user of the apparatus (201). The photodetector comprises a channel member (207) which may be made from graphene, respective source and drain electrodes (208, 209), a layer of photosensitive material (210) configured to vary the flow of electrical current through the channel member (207) on exposure to light from the light emitter (202), and a gate electrode (211). The apparatus (201) further comprises a layer of fluid-impermeable dielectric material (212) configured to inhibit a flow of electrical current between the channel member (207) and the gate electrode (211) of the photodetector (203) to enable the electrical conductance of the channel member (207) to be controlled by a voltage applied to the gate electrode (211) and to inhibit exposure of the light emitter (202) to fluid which has permeated through the fluid-permeable substrate (206). The layer of fluid-impermeable dielectric material (212) allows resilient substrates made from polymeric material to be used without the risk of damage to the overlying components caused by the permeated fluid. The dual functionality of the layer of fluid-impermeable dielectric material (212) reduces the number of fabrication steps used to form the apparatus (201) and results in a thinner, more compact device.

    摘要： An apparatus and method wherein the apparatus comprises: a deformable substrate;a curved support structure; at least one support configured to space the curved support structure from the substrate so that when the deformable substrate is deformed the curved support structure is not deformed in the same way; and a capacitive sensor comprising a protruding electrode capacitively coupled to an overlaying electrode;wherein the protruding electrode protrudes from a side of the curved support structure.

    摘要： An apparatus including a flexible substrate; and an overhanging electronic component island, the electronic component island configured to be less flexible than the flexible substrate and including one or more electronic components, wherein the electronic component island includes a substrate-face with a connection portion and an overhang portion, the connection portion being mechanically coupled to a surface of the flexible substrate via a single connection-support pad and the overhang portion configured to overhang and be substantially free of the underlying flexible substrate such that the underlying flexible substrate can be strained independently from the overhang portion under operational strains of the flexible substrate.

    摘要： A photodetector (400) has a two dimensional conductive channel (302, 408) with source and drain electrodes (404) configured to enable a flow of electrical current through the two dimensional conductive channel (302, 408); and a quantum dot layer (304, 406) overlying the two dimensional conductive channel (302, 408), the quantum dot layer (304, 406) configured to generate charge on exposure to incident electromagnetic radiation (310), the generated charge producing an electric field which causes a change in electrical current passing through the underlying two dimensional conductive channel (302, 408), the change in electrical current being indicative of one or more of the presence and magnitude of the incident electromagnetic radiation (310); wherein the quantum dot layer (304, 406) is configured to have an incident electromagnetic radiation surface (312) which has a texturing comprising undulations in the surface to provide a surface roughness with an average peak amplitude (308) of the order of between 10 nm and 300 nm. The surface texture increases the amount of electromagnetic radiation absorbed in the quantum dot layer (304, 406) in comparison to a photodetector having a flat (non-textured) incident electromagnetic radiation surface.
