摘要： A haptic detection apparatus includes: a capacitance detection unit that detects capacitance of each of capacitors which changes according to an external force applied to a second electrode plate of a capacitance-type load sensor; a distributed load measurement unit that measures a distributed load indicating a distribution of load applied to each of the cylinders on the basis of a change amount of the capacitance of each capacitor which is detected by the capacitance detection unit; and a load information calculation unit that calculates a total load and a load center position of the external force applied to the second electrode plate of the load sensor on the basis of a relation between an expansion/contraction amount of each cylinder relative to the distributed load measured by the distributed load measurement unit and a pattern of the distributed load.

摘要： A pair of first electrodes 111, 112 is arranged in a state being separated in a direction parallel to a contact surface 102 of a base material 10 made of a dielectric and being at least partially in contact with the base material 10. A pair of second electrodes 121, 122 is arranged in a state of overlapping at least one of the pair of first electrodes and sandwiching the base material 10 at a position farther from the contact surface 102 of the base material 10 than the pair of first electrodes 111 and 112 in a direction perpendicular to the contact surface 102 of the base material 10. The proximity state of an object Q with respect to the contact surface 102 of the base material 10 is detected according to the measurement result of the capacitance C1 between the pair of first electrodes 111 and 112.

摘要： A tool driver for use in robotic surgery includes a base configured to couple to a distal end of a robotic arm, and a tool carriage slidingly engaged with the base and configured to receive a surgical tool. In one variation, the tool carriage may include a plurality of linear axis drives configured to actuate one or more articulated movements of the surgical tool. In another variation, the tool carriage may include a plurality of rotary axis drives configured to actuate one or more articulated movements of the surgical tool. Various sensors, such as a capacitive load cell for measuring axial load, a position sensor for measuring linear position of the guide based on the rotational positions of gears in a gear transmission, and/or a capacitive torque sensor based on differential capacitance, may be included in the tool driver.

摘要： The enclosed describes a sensor pad for wearing on a human body. The sensor pad is configured to be in contact with a substrate having a contoured surface, such as a surface of the body. The sensor pad comprises at least a sensor layer and a stiffener layer. The sensor layer comprises a surface area defining a sensing area configured to measure value at a plurality of locations of the sensing area. The stiffener layer is couples to the surface area of the sensor layer. The stiffener layer has a micro-cut pattern to reduce mechanical resistance of the stiffener layer. The micro-cut pattern facilitates the stiffener layer in stretching or compressing in one or more predefined directions, enabling the stiffener lay to conform to the contoured surface of the substrate.

摘要： Aspects of the subject technology relate to a sensor device including a first cavity and a second cavity separated from the first cavity by a diaphragm. A first plate of the first cavity forms a first electrode of a capacitance. The diaphragm forms a second plate of the first cavity, which is the second electrode of the capacitance. The diaphragm is flexible and can deflect in response to an applied pressure.
