Abstract: A load cell body for transmitting forces and moments in plural directions includes a rigid central hub having a central axis and a rigid annular ring concentric with the central hub about the central axis. At least three radial members extend radially with respect to the central axis along corresponding longitudinal axes from the central hub to the annular ring where each radial member includes a center body with an aperture extending there through along an aperture axis that is parallel to the central axis. A first flexure joins the center body to the central hub, while a second flexure joins the center body to the annular ring.

Abstract: The present disclosure concerns a pressure sensor, comprising at least two adjacent electrically conductive leads disposed in a pattern on a face of a first elastomeric carrier; and an electrically resistive layer formed of a electrically resistive composite material for shunting the at least two adjacent electrically conductive leads, said electrically conducting layer disposed on a face of a second elastomeric carrier. The first and second carriers are stacked across a spacer such that the at least two adjacent electrically conductive leads faces the electrically resistive layer across a gap defined by the spacer. The gap is formed by a pocket between the carriers. The first carrier including the at least two adjacent electrically conductive leads and/or the second carrier including the electrically resistive layer are stretchable such as to upon receiving a force, exerted in a direction across the gap, reduce the gap between the electrically resistive layer and the at least two adjacent electrically conductive leads. Upon closing the gap the adjacent electrically conductive leads are shunted over a force dependent contact area and contact resistance. A gas in a gas confining structure between the carriers at least partly counteracts the exerted force.

Abstract: Disclosed are a flexible strain sensor and a method for manufacturing the same. A conductive line pattern is directly printed on a flexible substrate by jetting a printing material mixture of metal nanoparticles and CNTs at a high impact speed, and sandwiched between the flexible substrate and a flexible cover. The mixture is excited by aerodynamically controlling pumping timing and jetted onto the flexible substrate in an aerosolized state through a nozzle. The jetted mixture collides with the surface of the flexible substrate to create cracks, and then CNTs penetrate into the cracks and are mechanically locked with the flexible substrate. Subsequently, metal nanoparticles and CNTs are deposited thereon to a predetermined width and height, forming the conductive line pattern. This direct printing can be performed in a low pressure and at room temperature without using solvents or resins, thus no need for additional chemical post-treatment or heat treatment.

Abstract: A force sensor includes a force receiver which receives a force or a moment that acts on a detection target part, and a strain element which is provided to a sensor base and which serves as an elastic support that supports the force receiver. The force sensor includes two systems of detecting sections which each independently detect strain of four beam parts of the strain element, two systems of computing circuits which each independently compute, on the basis of a detection result that has been outputted from a corresponding one of the two systems of detecting sections, the force or the moment that acts on the detection target part, and two systems of output sections which each independently output, as an electrical signal, a computation result that has been outputted from a corresponding one of the two systems of computing circuits.

Abstract: Provided is a force sensor capable of expanding the application range of an electrically conductive member having an isotropic gauge factor. The electrically conductive member is placed in a designated latitude region on a main face of the strain body to annularly extend around a pole and to be divided at a position. The designated latitude region is a latitude region in which the magnitude of the sum of a first strain amount in the longitude line direction of the strain body relative to the pole and a second strain amount in the latitude line direction is not less than a reference value when a force having a component in the perpendicular direction to the main face is applied to the strain body.
