    摘要： Provided is a relatively easy-to-fabricate piezoelectric power generating element capable of generating a large amount of electric power while comprising a bridge-type vibration beam that is resistant to damage from external vibration. This element comprises a support member, a strip-shaped vibration beam, a piezoelectric layer, and electrodes. The first and second ends of the vibration beam are fixed to the support member. The piezoelectric layer and the electrodes are provided on the surface of the vibration beam. The vibration beam extends in a plane when it is not vibrating. The vibration beam has a first portion that extends from the first end fixed to the support member, a second portion that extends from the second end fixed to the support member, and a third portion that connects the end of the first portion opposite to the first end and the end of the second portion opposite to the second end. The vibration beam has a shape such that, when viewed in a direction perpendicular to the plane, a first direction in which the first portion extends is a direction closer to the second end, and a second direction in which the second portion extends is a direction closer to the first end, the first and second directions each make an angle of more than 0° and less than 90° with respect to a straight line connecting the center of the first end and the center of the second end, and the third portion intersects once the straight line.

    摘要： The invention provides a power generation method using a thermoelectric element, a thermoelectric element, and a thermoelectric device that excel in thermoelectric performance and are applicable to a wider range of applications over conventional counterparts. The element includes a first electrode and a second electrode that are disposed to oppose each other, and a laminate interposed between the first and second electrodes and electrically connected to both of the electrodes. The laminate has a structure in which a Bi layer and a metal layer made of a metal other than Bi are alternately layered, and the Bi layer and the metal layer having layer surfaces that are slanted with respect to a direction in which the first and second electrodes oppose each other. The element generates a potential difference between the electrodes by a temperature difference created along a direction perpendicular to the opposing direction of the first and second electrodes in the element. The power generation method and the thermoelectric device use this element.

    摘要： The present invention provides an electric power generation method using a thermoelectric power generation element, a thermoelectric power generation element, and a thermoelectric power generation device, each of which has higher thermoelectric power generation performance than conventional ones and can be used for more applications. The thermoelectric power generation element includes a first electrode and a second electrode that are disposed to oppose each other, and a laminate that is interposed between the first and second electrodes and that is electrically connected to both the first and second electrodes, where the laminate has a structure in which Bi2Te3 layers and metal layers containing Al, Cu, Ag, or Au are laminated alternately, a thickness ratio between the metal layer and the Bi2Te3 layer is in a range of metal layer:Bi2Te3 layer=400:1 to 20:1, lamination surfaces of the Bi2Te3 layers and the metal layers are inclined at an inclination angle θ of 15° to 60° with respect to a direction in which the first electrode and the second electrode oppose each other, and a temperature difference applied in a direction perpendicular to the direction in the element generates a potential difference between the first and second electrodes. The electric power generation method and thermoelectric power generation device each use the element.
