  • Patent number: 11502239
    Abstract: Technologies for a microelectromechanical system (MEMS) made up of composable piezoelectric actuators is disclosed. An elongated piezoelectric rod is disposed between a top and a bottom electrode. The top electrode runs along one edge of the top of the piezoelectric rod for a first segment, then runs along the other edge of the top of the piezoelectric rod for the a second segment. When a voltage is applied across the electrodes, the piezoelectric rod bends in a first direction for the first segment and in a second direction opposite the first for the second segment, displacing the tip of the rod. Several such rods can be joined in parallel and/or series, allowing for large-scale systems to be composed.

Further, the gap and the resin film reduces the vibrations from the diaphragm reaching an operation surface. Thus, the user feels the vibrations of the diaphragm via only a finger which has pushed the resin film until the resin film contacts the upper surface of the diaphragm, and the other fingers hardly feel the vibrations.

  • Patent number: 10816152
    Abstract: A body defines an interior region and an exterior region. A liquid-retaining portion retains a liquid. A mist generator transforms the liquid into a mist. A first chamber receives the mist to form mist-infused fluid. A fan applies pressure to fluid in the second chamber. A first fluid-transferring portion: receives at an inlet the mist-infused fluid from the first chamber in the interior region; emits the mist-infused fluid into the exterior region via an outlet; and changes the velocity of the mist-infused fluid between the inlet and the outlet. A second fluid-transferring portion receives at an inlet the fluid from the second chamber in the interior region and emits this fluid into the exterior region via an outlet. A light source emits light to illuminate the mist-infused fluid in the exterior region.

  • Patent number: 10804818
    Abstract: A triboelectric generator includes a resiliently-deformable hexagonal housing including a first housing wall and a second housing wall positioned opposite the first housing wall. A first electrode resides along the first housing wall, and a second electrode resides along the second housing wall. A dielectric contact layer is positioned in intimate contact with the first electrode and between the first electrode and the second electrode. The dielectric contact layer is spaced apart from the second housing wall. The first housing wall is coupled to the second housing wall such that at least one of the first housing wall and the second housing wall is resiliently movable toward the other one of the first housing wall and the second housing wall so as to enable contact between the dielectric contact layer and the second electrode during operation of the triboelectric generator.

  • Patent number: 10797217
    Abstract: A bending actuator device or sensor device for sensing bending comprises a stack of electroactive polymer units. The adjacent electroactive polymer units in the stack are slidable relatively to each other. This means that, for an actuator for example, an increased actuation force is enabled without requiring increased driving voltage, and it also avoids the problems of stress build up by allowing sliding between the units.
