Abstract: The present invention is a piezoelectric actuator drive method, a piezoelectric actuator drive circuit, and a piezoelectric actuator drive system capable of causing a piezoelectric element to vibrate in a maximum amplitude state. The piezoelectric actuator drive circuit includes: an obtainment unit that obtains operation information pertaining to operation of the piezoelectric element in a period that is a part of one cycle of a drive cycle in which the piezoelectric element is driven; and a control unit that performs feedback control of a drive parameter for driving the piezoelectric element based on the operation information.

Abstract: [Object] To provide a technology that enables one user to appropriately recognize a tactile sensation based on a force from the other user.
[Solving Means] A tactile presentation apparatus according to the present technology includes a first detection unit, a first presentation unit, and a control unit. The first detection unit detects a first detection value based on a force of a first user. The first presentation unit is provided at a position other than a position of the first detection unit and presents a tactile sensation to the first user. The control unit controls the first presentation unit to present a tactile sensation to the first user on the basis of a second detection value of another tactile presentation apparatus, the other tactile presentation apparatus including a second detection unit that detects a second detection value based on a force of a second user and a second presentation unit that presents a tactile sensation to the second user.

Abstract: [Object] To provide a fluid control apparatus having a diaphragm structure and small flow path resistance.
[Solving Means] A fluid control apparatus according to the present technology includes a first space, two flat plate members, a drive mechanism, a second space, a first check valve, and a second check valve. The first space has an inlet and an outlet. The two flat plate members face each other via the first space, and at least one of the flat plate members is an elastic body having flexibility. The drive mechanism bends the elastic body. The second space adjoins the first space, communicates with the first space via the inlet, and has a suction port. The first check valve allows fluid to flow from the suction port to the first space via the inlet. The third space adjoins the first space, communicates with the first space via the outlet, and has a discharge port. The second check valve allows the fluid to flow from the first space to the discharge port via the outlet. At least one of the suction port and the discharge port is positioned on an extension surface of at least one of the two flat plate members.

Abstract: [Object] To provide a tactile sense presentation apparatus, an electronic apparatus, an accessory, and a holding apparatus that can achieve an improvement in mountability.
[Solving Means] A tactile sense presentation apparatus according to an embodiment of the present technology includes a mounting portion, a pump unit, and a control unit. The mounting portion is mounted on a target object and includes a surface material which is deformable in at least a part of a contact portion with the target object. The pump unit includes a flow path, which is connected to the mounting portion, and feeds a fluid for deforming the surface material to the mounting portion. The control unit controls driving of the pump unit.
