Abstract: Disclosed is a wearable device including a link unit which has a shape corresponding to the lower extremities of the wearer and rotates in a front-rear direction, and a power supply unit. The link unit includes a right link unit fixed to the right lower extremity of the wearer and has a lower end that comes into contact with the ground, and a left link unit which is fixed to the left lower extremity of the wearer and has a lower end that comes into contact with the ground. A steering mode is provided to steer the link unit, and during the steering mode, i) the power supply unit supplies power to space the right link unit and the left link unit apart from each other, and then ii) the power supply unit supplies power in a direction to cause a unit to be rotated rearward.

Abstract: A capacitive pressure sensor includes a first electrode and a second electrode disposed on a surface of a folded flexible substrate. The first and second electrodes face each other and are separated from each other by a dielectric layer. The sensor can operate by generating an electrical signal related to a change in capacitance between the first and second electrodes. The change in capacitance results from a change in thickness of the dielectric layer due to an external pressure. The electrical signal can be transmitted from the capacitive pressure sensor to an external device.

Abstract: A manufacturing method of a capacitive pressure sensor includes attaching a first electrode and a second electrode onto a first surface of a flexible substrate, attaching a signal processing unit to the flexible substrate, forming a dielectric layer over the first electrode or the second electrode, and folding the flexible substrate so that the first electrode and the second electrode face each other with the dielectric layer being disposed therebetween.

Abstract: Provided is a joint structure for a robot including: a body part; a link structure connected to an upper portion of the body part and including multiple links; a sensor unit provided on one end of the link structure; a first wire having one end connected to the sensor unit; and an actuator fixed to one side of the body part and connected to the other end of the first wire to move the other end of the first wire in a vertical direction, wherein the sensor unit measures tension applied to the first wire.

Abstract: A force generating device includes: a support unit; a link unit rotatably coupled to one side of the support unit; a transfer unit that is coupled to the link unit and transfers wave energy to the outside; and a drive unit that operates the link unit. In particular, the transfer unit is moved on an imaginary sphere by a motion of the link unit, and the transfer unit transfers the wave energy to a center of the imaginary sphere.

Abstract: A capacitive pressure sensor includes a flexible substrate, a first electrode and a second electrode disposed on one surface of the flexible substrate so as to be spaced apart from each other and located to face each other when the flexible substrate is folded, a dielectric layer interposed between the first electrode and the second electrode, and a signal processing unit disposed on one surface of the flexible substrate and converting a capacitance, which changes as a thickness of the dielectric layer changes by external pressure in a state in which the flexible substrate is folded, into an electrical signal.
