摘要： A junctionless Nano-Electro-Mechanical (NEM) resonator, comprising a highly doped conductive channel connecting a drain region and a source region; the conduction channel region is movable and the overall structure is fixed at least at these two ends placed on acting the source and drain regions, respectively; at least one fixed gate electrode arranged to control a depletion charge in the highly doped conductive channel thereby modulating dimensions of a cross-section of the highly doped conductive channel. A dimension of the cross-section in the direction of an electrical field that is oriented from the fixed gate electrode to the highly doped conductive channel, is designed in such a way that it can be reduced under the effect of the depletion charge such that a full depletion in the highly doped conductive channel is achievable with the control of the fixed gate electrode.

摘要： There is provided a displacement sensor which can precisely detect the amount of displacement given by an operator. A touch sensor which is a type of the displacement sensor has a piezoelectric element, a voltage converting unit and a detecting unit. The piezoelectric element instantaneously generates a voltage proportional to a pressing force (the amount of pressing). The voltage converting unit converts the voltage generated by the piezoelectric element, into a voltage proportional to a transition determined based on a predetermined time constant determined by an impedance of a resistor of the voltage converting unit and capacitances of a capacitor and the piezoelectric element, and a pressing force. The detecting unit integrates output voltages of the voltage converting unit, and calculates the pressing force (the amount of pressing) based on an integration value.

摘要： A planar integrated MEMS device has a piezoelectric element on a dielectric isolation layer over a flexible element attached to a proof mass. The piezoelectric element contains a ferroelectric element with a perovskite structure formed over an isolation dielectric. At least two electrodes are formed on the ferroelectric element. An upper hydrogen barrier is formed over the piezoelectric element. Front side singulation trenches are formed at a periphery of the MEMS device extending into the semiconductor substrate. A DRIE process removes material from the bottom side of the substrate to form the flexible element, removes material from the substrate under the front side singulation trenches, and forms the proof mass from substrate material. The piezoelectric element overlaps the flexible element.

摘要： This invention provides an electricity generation device capable of generating electricity using kinetic energy generated by spontaneous behavior of an animal. The device includes a mechano-electric conversion mechanism that converts a displacement of a body part where the animal spontaneously moves (for example, a mouth) into an electric energy. For example, the mechano-electric conversion mechanism can have an arrangement for converting the displacement of the body part into rotation by a combination of a rack and a gear and rotating the rotor of a dynamo or an alternator.
