摘要： A sensor unit to be incorporated in a skin-like layer of machines such as robots employs a set of sensor electrodes supported in a first deformable sheet and a base electrode supported in a second deformable sheet, each of the sensor electrodes partially overlapping the base electrode so that application of a shear force causes the overlap of the electrodes to differentially change modifying the capacitance of the electrodes and permitting the detection of the shear force.

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 sensor for detecting and distinguishing between increasing and decreasing proximity of a pointing element, touch by a pointing element, pressure applied by a pointing element, stretching (and/or other deformation) of the sensor, and any of the above while stretching and/or otherwise deforming the sensor. The sensor may comprise a cluster sensor unit having a first sensor and a second sensor wherein the first sensor has a higher ratio of distal flux to proximate flux as compared to the second sensor. With this flux characteristic, the first sensor is relatively more sensitive (as compared to the second sensor) to proximity of a pointing element, while the second sensor is relatively more sensitive (as compared to the first sensor) to force and/or pressure applied by the pointing element.

摘要： An electrostatic capacity sensor 1 capable of expanding a force detectable region includes an upper electrode 11, a lower electrode 11 for detecting electrostatic capacity C between the lower electrode 11 and the upper electrode 11, and a base material 12 having dielectric properties and elasticity and disposed between upper and lower electrodes 11 and 11. An upper base material layer portion 12a and a lower base material layer portion 12b of the base material 12 are configured such that elastic deformation amounts when the same force is applied are different from each other.

摘要： A sensor unit for detecting bending of the sensor unit comprises: a capacitive upper sensor having an upper capacitance and comprising first and second deformable upper electrodes spaced apart from one another in a Z direction, the first and second upper electrodes respectively having first and second upper shapes; and a capacitive lower sensor having a lower capacitance, spaced apart from the upper sensor in a Z direction and comprising first and second deformable lower electrodes spaced apart from one another in the Z direction, the first and second lower electrodes respectively having first and second lower shapes. For a bend of the sensor unit in a first direction, the first and second upper shapes change such that the upper capacitance decreases and the lower shapes change such that the lower capacitance increases. For a bend of the sensor unit in a second direction opposed to the first direction, the first and second upper shapes change such that the upper capacitance increases and the lower shapes change such that the lower capacitance decreases.

摘要： An apparatus provides tactile stimulus to a human user using a tri-layer actuator comprising: first and second polymer layers which are electronically and ionically conductive and have one or more dimensions which vary in dependence on insertion of ions therein and withdrawal of ions therefrom; and a deformable layer located between the first and second polymer layers to physically separate the first and second polymer layers from one another, the deformable layer electronically insulating and ionically conductive. Application of first and second voltages between the first and second polymer layers creates corresponding first and second distributions of ions within the first and second polymer layers. Changing between application of the first and second voltages causes corresponding deformation of the tri-layer actuator between corresponding first and second shapes, a difference or transition between the first and second shapes detectable by a sense of touch of a human user.

摘要： A triaxial force sensor 1 includes nine first electrodes 11 to 19, and nine second electrodes 21 to 29 attached to an electrode support 10 in such a manner that the electrode support 10 is interposed between the nine first electrodes 11 to 19 and the nine second electrodes 21 to 29. A pair of first electrodes 14 and 16 are arranged such that a straight line connecting the two is orthogonal to a straight line connecting a pair of first electrodes 12 and 18, and the second electrodes 22, 24, 26, and 28 are arranged such that the respective halves overlap the first electrodes 12, 14, 16, and 18 in plan view. The sensor has a number of components and size, thereby allowing a reduction in manufacturing cost, in the case of detecting forces in orthogonal triaxial directions.
