  • Patent number: 10561833
    Abstract: A conductive pad for pain relieving and muscle training, comprises an electrode sheet electrically connected to a control unit and a conductive gel for attaching onto the human body. The conductive gel is added with a substance for pain relieving and muscle training, which is capsaicin, menthol, lidocaine, or other substitutes in an amount of 0.001% to 30% by mass. This invention has the function of increasing the blood circulation/local anesthesia by adding capsaicin, menthol, lidocaine, or other substitutes to the conductive gel, and has the effect of pain relieving and muscle training. The conductive pad that is made of the above described conductive gel can be used alone, and also be used with all of the TENS/EMS units in the market, offering a wide range of application. In addition, this invention does not require the additional heating source, simplifies the structure, and greatly reduces the manufacturing costs.

    Abstract: The invention relates to a bistable piezoelectric cantilever-based vibration energy harvester that increases the energy harvested over a broad frequency of vibrations by introducing bistability to the cantilever through use of two repelling magnets, one mounted on the cantilever and one at a location facing the first. This increases the amplitude and velocity of cantilever vibration, hence harvested power, while nonlinearity makes the system efficient over almost the entire range of frequencies, lower than the natural resonant frequency of the linear version without the magnets. Such improved performance is seen while the cantilever remains in the bistable mode.

  • Patent number: 10166400
    Abstract: Provided is a method for separating a nanogenerator, which includes laminating a buffer layer on a sacrificial substrate, making a nanogenerator on the buffer layer, laminating a metal layer on the nanogenerator and separating the nanogenerator from the buffer layer. Here, a nanogenerator is separated by using a stress difference between the sacrificial substrate and the metal layer, instead of an existing method in which a nanogenerator is separated from the sacrificial substrate by means of wet etching or the like. In particular, according to a difference between a tensile stress at the metal layer such as nickel and a compressive stress at the lower silicon substrate, the nanogenerator is intactly separated from the silicon oxide layer serving as a buffer layer. Therefore, the nanogenerator may be separated from the sacrificial substrate in a mechanical way, which is safer and more economic in comparison to an existing chemical separation method using an etching solution.

  • Patent number: 10113529
    Abstract: An apparatus for converting wave energy into electrical energy including a float element excited at a defined frequency by the waves. A power extraction system collaborates with the float element to convert mechanical energy into electrical energy, the mechanical energy coming from the movement of the float element excited by the waves. The power extraction system takes the form of a frequency amplifier made up of at least two piezoelectric motors each composed of at least one piezoelectric post excited at a frequency higher than that of the float, and a member for activating said piezoelectric motors acting on the piezoelectric motors so as to squash said piezoelectric posts. Each piezoelectric motor has a mechanical amplification device connected to rollers and includes a) jaws able to apply mechanical stress to the posts, b) a lever acting on the jaws with a proximal end connected to said jaws and a distal end connected to a roller in contact with the member so as to activate said piezoelectric motor.

  • Patent number: 10096765
    Abstract: A piezoelectric energy harvester has a box, a plurality of first arc-shaped metal stands and a plurality of arc-shaped piezoelectric elements. The box has an upper portion, a connection base, a buffer element and a lower portion. The connection base situates between the upper portion and the lower portion. The upper portion movably connects with the lower portion through the buffer element. The plurality of first arc-shaped metal stands situated on a side of the connection base in the box. Each of the arc-shaped piezoelectric elements locates on each of the first arc-shaped metal stands. When an external force applied on the box, the plurality of first arc-shaped metal stands deforms due to the compression from the upper portion and consequently causes the deformation of the arc-shaped piezoelectric elements for generating electricity accordingly.
