Abstract:
A tactile sensor comprises: a first sheet having at least either flexibility or elasticity; and a second sheet having at least either flexibility or elasticity and having a first surface facing the first sheet and a second surface opposite to the first surface. The second surface includes a plurality of protruding shapes. Each of the plurality of protruding shapes includes an enclosed space inside, the enclosed space being defined by the first surface of the second sheet and the first sheet. At least one first electrode pattern is disposed on the first sheet in the enclosed space of each of the plurality of protruding shapes. At least one second electrode pattern is disposed on the first surface in the enclosed space of each of the plurality of protruding shapes.
Abstract:
A flexible substrate is provided with: a stretchable sheet; a member located on the sheet; and a stretchable strip connected to the member, and located on the sheet. When the amount of extension of the sheet is equal to or less than a predetermined value, the sheet has a first elastic modulus, and when the amount of extension of the sheet exceeds the predetermined value, the sheet has a second elastic modulus that is greater than the first elastic modulus and greater than the elastic modulus of the strip.
Abstract:
An electronic part package comprises a sealing resin layer, an electronic part and a metal plating pattern layer. The sealing resin layer is provided with a principal surface including a first region that has a bellows-like shape having alternate ridges and valleys and a second region that is flat. The electronic part includes an electrode having a principal surface and is covered by the sealing resin layer except the principal surface, which is surrounded by the second region. The metal plating pattern layer is integrally provided on the first and second regions and on the principal surface of the electrode. A portion of the metal plating pattern layer, the portion located on the first region, has a bellows-like shape having alternate ridges and valleys along an outline of the first region.
Abstract:
A stretchable flexible substrate includes a film base. At least a portion of the film base includes a rolled part. The rolled part includes a first curved part having a curved shape in which the film base is folded back with one main surface of the film base facing inward, a second curved part having a curved shape in which the film base is folded back with another main surface of the film base facing inward, and a base layered part located outside the first curved part and the second curved part. The base layered part has a shape in which the film base is rolled in such a way that a portion of the film base that is contiguous with the first curved part and another portion of the film base that is contiguous with the second curved part are layered on one another.
Abstract:
A flexible substrate includes a plurality of unit wiring structures and an insulation sheet on which the plurality of unit wiring structures are disposed. Each of the plurality of unit wiring structures includes a central section and a plurality of strips disposed at an outer side of the central section. Each of the plurality of strips has a first end and a second end, and is curved along an outer periphery of at least part of the central section, the first end connected to the central section. The plurality of strips in each of the plurality of unit wiring structures curve in a clockwise or a counterclockwise manner with the central section as a center of rotation. The plurality of unit wiring structures include at least four unit wiring structures arranged in a two-dimensional manner.
Abstract:
A biological sensor includes: a first sheet that has flexibility and/or stretchability; and a second sheet that has flexibility and/or stretchability. The second sheet has a first surface facing the first sheet, and a second surface opposite to the first surface. The second surface has a plurality of projections that are configured to be brought into contact with a living body to obtain information on the living body. In the second surface, at least part of each of the plurality of projections has conductivity. In the first surface, a portion surrounding each of the plurality of projections is bonded to the first sheet. Within each of the plurality of projections, an enclosed space defined by the first surface of the second sheet and the first sheet is present
Abstract:
A flexible substrate includes unit wiring structures including first and second unit wiring structures that are mutually adjacent. Each of the unit wiring structures includes a central section and one or more strips. Each of the one or more strips has first and second ends. The first end is connected to the central section. The second end of at least one of the one or more strips of the first unit wiring structure and the second end of at least one of the one or more strips of the second unit wiring structure are mutually connected. The flexible substrate includes a gap between a side surface of the mutually connected strips and a side surface of the central section of the first or the second unit wiring structure, and/or between a side surface of the mutually connected strips and a side surface of another strip.
Abstract:
A flexible substrate includes a plurality of unit wiring structures. Each of the unit wiring structures includes: a central section; and at least four curved strips disposed at an outer side of the central section, each of the curved strips having a first end connected to the central section. The central section includes: an insulation layer; interlayer connection via that passes through the insulation layer; first wiring section connected to the interlayer connection via; and second wiring section electrically connected to the first wiring section by way of the interlayer connection via. The first wiring section, insulation layer and second wiring section are disposed in this order, and two of the at least four curved strips extending in a first direction are connected to the first wiring section, other two of the at least four curved strips extending in a second direction are connected to the second wiring section.
Abstract:
A substrate is provided with: a stretchable sheet; a plurality of members located on the sheet; a plurality of strips that are stretchable, and that connect the plurality of members; and a plurality of fiber threads that sew the plurality of members and the sheet together.
Abstract:
