A multi-axial tactile sensor for detecting forces in directions of three axes and a moment about at least one axis includes at least four sensor elements including at least three shearing force detecting elements having beam structures provided with a first resistive layer and a second resistive layer at specific portions, and at least one pressing force detecting element having a beam structure provided with a third resistive layer and a fourth resistive layer at specific portions, the beam structures of the four sensor elements being arranged on a sensor substrate so that their respective longitudinal directions are radially arranged, and the moment about at least one axis is detected based on outputs of two or more sensor elements being arranged at positions of rotational symmetry around the center of the radial arrangement of the plurality of sensor elements.

Multi-axial tactile sensor

A tactile sensor and a multi-axial tactile sensor are provided, each of which is thin and can measure shearing force. A multi-axial tactile sensorincludes a sensor elementprovided in a plane substantially at the same level as the surface of a substrate, and an outer package membercovering around the sensor elementand transmitting external force to the sensor element. The sensor elementincludes a flexible beam() having at least one end supported by the substrate. The sensor elementdetects deformation of the beam(), the deformation being caused in the direction in parallel with the surface of the substrate

Tactile sensor and multi-axial tactile sensor

To provide a vehicle having high operability and its control method. A vehicle includes a passenger seat on which a passenger rides on, a chassis that support the passenger seat, wheels that move the chassis, a force sensor that outputs a measurement signal according to a force exerted on a seat surface of the passenger seat, a drive unit that drives the passenger seat so as to change an angle of the seat surface of the passenger seat, and a control calculation unit that calculates a reference input used to drive the wheels and the drive unit based on a drive amount of the drive unit, a balanced position posture of the passenger seat, and the measurement signal from the force sensor.

Vehicle and its control method

A plurality of three-dimensional structure configuring devices, each including an elastic body in which micro three-dimensional structure elements fixed to a substrate member are placed so as to be covered therewith and which is fixed to the substrate member, are placed within a film-like elastic body with the substrate members thereof spaced apart from one another so as to configure a three-dimensional structure. Thereby, the plurality of three-dimensional structure configuring devices can be placed with desired intervals of arrangement and in desired positions within the film-like elastic body and so that various specifications can be addressed.
