Abstract: A tactile sensor-attached finger is mountable on a robotic hand to reduce damage and failure caused by a grip target coming in contact with a part of a finger member other than its palm surface. A tactile sensor-attached finger (1F) for a robot hand for gripping a grip target includes a finger member (2) including a palm surface (21a) to be in contact with the grip target, a back surface (21b) opposite to the palm surface (21a), an end surface (21c) adjacent to the palm and back surfaces (21a, 21b) on ends of the palm and back surfaces (21a, 21b) in an extension direction in which the palm and back surfaces (21a, 21b) extend, and two side surfaces (21d) adjacent to the palm and back surfaces (21a, 21b) in a direction intersecting with the extension direction, and a tactile sensor (5) being a film attached to an outer surface of a housing (21) included in the finger member (2) and including a pressure-sensitive area (5a) overlapping the palm surface (21a) and at least one of the end surface (21c), one of the two side surfaces (21d), or the other of the two side surfaces (21d).

Abstract: Each of a first electrode pattern Ty and a second electrode pattern Tx extends between third electrodes Rx neighboring in a Y direction among the plurality of third electrodes Rx so as to overlap only partly with each of the neighboring third electrodes Rx in a plan view. A microcontroller is configured to detect capacitance generated at those portions. The microcontroller is configured to calculate shear force based on a capacitance change obtained due to a change in an overlapping surface area between the third electrode Rx and the first electrode pattern Ty and the second electrode pattern Tx overlapping each other in a plan view, when a pressure is applied so that an insulator is deformed.

Abstract: A capacitive pressure sensor is disclosed. The capacitive pressure sensor includes a first electrode sheet, a second electrode sheet, an elastic body layer formed by a foam sheet in which air bubbles having an average air bubble diameter of 2 to 40 μm are dispersed and sandwiched between the first electrode sheet and the second electrode sheet, and adhesive layers, one adhesive layer being formed on a surface of the elastic body layer on a side of the first electrode sheet and another adhesive layer being formed on a surface of the elastic body layer on a side of the second electrode sheet.

Abstract: To provide an information input device excellent in durability and visibility and configured to detect a shear force, the information input device of the present invention includes a cover panel, a housing including a support portion that supports a peripheral edgeof the cover panel from a back surface, a frame-shaped shear force sensor disposed between the peripheral edge of the cover panel and the support portion of the housing and detects a horizontal input with respect to a surface of the cover panel, and a detection circuit connected to the shear force sensor. The frame-shaped shear force sensor has a layered body including a band-like first electrode, an elastic member, and a pair of band-like second electrodes disposed so as to partially overlap with the first electrode.

Abstract: A thin and durable detection unit for a shear force sensor is disclosed. The detection unit detects shear forces in a plurality of directions. A detection circuit is connected to a first electrode layer and a second electrode layer. First driving electrodes and second driving electrodes insulated from each other by first isolation trenches are formed in the first electrode layer. The second driving electrodes also serving as third driving electrodes and the first driving electrodes also serving as fourth driving electrodes insulated from each other by second isolation trenches are formed in the first electrode layer. First detection electrodes and second detection electrodes are formed in the second electrode layer.

Abstract: A touch panel includes: first electrodes disposed in parallel at a position corresponding to a viewing area of a panel member and have a capacitance changing according to a proximity of an object to be detected; second electrodes that intersect with the first electrodes, are disposed in parallel, and similarly change in capacitance; third electrodes disposed in parallel between the first or second electrodes and have electrical resistances changing according to posture and temperature; and fourth electrodes extending along the respective third electrodes and similarly change in electrical resistance. A resistance change rate of the fourth electrodes due to temperature is the same as for the third electrodes. The resistance change rate of the fourth electrodes due to the posture change is 90% or less than for the third electrodes due to the posture change. This allows a pressing force to be accurately measured.
