摘要： A micro-electro-mechanical generator has a liquid chamber, a heating block, an elongated elastic piezoelectric plate and a pair of electrodes. The liquid chamber is defined by bottom blocks which include the heating block and side walls, and can maintain a liquid. The heating block generates bubbles within the liquid chamber. The elongated elastic piezoelectric plate has a piezoelectric material layer, and is positioned in the liquid chamber adjacent to an upper portion of the heating block. The elongated elastic piezoelectric plate is deformable by contact with the bubbles, wherein a first end of the elongated elastic piezoelectric plate is a free end and a second end of the elongated elastic piezoelectric plate is a fixed end. The pair of electrodes are electrically connected to the piezoelectric material layer.

摘要： A micro-electro-mechanical generator has a housing, a heater, a cooler, a heat transfer member, a supporting member, and fluid. The heater is formed in the housing and the cooler is formed in the housing opposite to the heater. The heat transfer member is positioned between the heater and the cooler and is provided with a first surface facing the heater and a second surface facing the cooler. The supporting member supports the heat transfer member at an external portion of the heat transferring member and is deformable between a first position where the heat transferring member is positioned adjacent to the heater, and a second position where the heat transferring member is positioned adjacent to the cooler. The supporting member also partitions the housing into a sealed first space at a side of the heater and a second space at a side of the cooler. The fluid is charged in the sealed first space. Electric energy is obtained whenever the deformation of the supporting member provided with a piezoelectric element.

摘要： A method of extracting electrical energy from mechanical motion includes reusing an elastic portion of energy in a transducer by transferring the elastic portion of energy to another transducer. An apparatus for extracting electrical energy from mechanical motion includes at least two transducers coupled such that an elastic portion of energy in one transducer is transferable to the other transducer. The transducers are coupled by a member defining a waved surface, and each transducer defines a coupler in contact with the waved surface for movement following the waved surface. Couplers of two transducers are positioned such that they move out-of-phase relative to each other. The transducers are bound to a plate positioned between members such that the plate is deformed. The plate and members are configured such that relative rotation therebetween produces a wave that travels along the plate.

摘要： The invention relates to a method and apparatus that provide autonomous power supply by converting energy of sources of a non-electrical nature into the electric energy using charge generators. For such apparatuses, as charge generators can be used piezoelectric elements, triboelectric elements, as well as radioactive sources of charged particles that do not require periodic replacement of re-charging—in contradistinction to the convention sources of power supply, galvanic batteries. Charge generator (1), when activated, produces a portion of electric charges q having a high electric potential Uin, which portion is applied to the input of charge energy converter (2). The function of the converter (2) is to increase the initial value of charges q up to value of Q, with simultaneous reduction of their potential to Uout value, which less than Uin. For the purpose to store charges Q obtained as a result of the conversion, which charges Q are needed for the electronic systems power supply, electric charge storage (3) is positioned at the output of the apparatus.

摘要： A piezoelectric active-mode incrementor switch system (100) includes two ratchet wheels (118, 124) that are rotationally mounted on a drive shaft (112) having a knob (102). The ratchet wheels (118, 128) form a slipping clutch with their respective drive wheels (116, 128) which are rigidly mounted to the drive shaft and mechanically loaded with spring (120). The ratchet wheels (118, 124) are mounted inversely to each other on the drive shaft (112) and make contact with their respective cantilever beams (114, 136) which each have a piezoelectric film. In operation, the switch (100) functions by mechanically stimulating the piezoelectric beams. When the knob (102) is rotated in one direction, only one of the beams (114, 136) is displaced causing a generation of an electrical charge that acts as a signal. The other beam (114 or 136) is prevented from moving and therefore its beam does not produce a signal. When the knob (102) is rotated in the opposite direction, the other beam that was previously prevented from moving is displaced causing an electrical signal to be generated by the switch.
摘要翻译：压电有源模式增量开关系统（100）包括两个棘轮（118,124），其旋转地安装在具有旋钮（102）的驱动轴（112）上。棘轮（118,128）与其相应的驱动轮（116,128）形成滑动离合器，其刚性地安装到驱动轴并机械地装载弹簧（120）。棘轮（118,124）在驱动轴（112）上彼此相反地安装，并与其各自具有压电膜的各自的悬臂梁（114,136）接触。在操作中，开关（100）通过机械地激励压电波束来起作用。当旋钮（102）沿一个方向旋转时，只有一个光束（114,136）被移位，导致产生充当信号的电荷。防止另一个光束（114或136）移动，因此其光束不产生信号。当旋钮（102）沿相反方向旋转时，先前防止移动的另一个光束发生位移，导致开关产生电信号。
