摘要： A PCB-integrated electromagnetic-induction-principle-based power-line magnetic field energy harvester includes a PCB, the PCB including a substrate and a coil; a rotatable permanent magnet assembly, rotatably embedded in the middle through hole; and a fixed permanent magnet arranged opposite the rotatable permanent magnet assembly and providing the rotatable permanent magnet assembly with a direct current bias magnet field. The PCB-integrated electromagnetic-induction-principle-based power-line magnetic field energy harvester is driven by both of the AC magnetic field generated by the power line and the DC bias magnetic field generated by the fixed permanent magnet. The magnetic field energy around the power line is thus converted into the mechanical energy of the rotatable permanent magnet. The mechanical energy is then converted into the electric energy in the coil. The electric energy is supplied to the following low-power electronic devices (e.g. sensors) in a power transmission system.

摘要： The present disclosure provides a vibration motor. The vibration motor includes a housing having a bottom wall and a side wall, a vibrator received in the housing, and an elastic member supporting vibration of the vibrator. The side wall includes a first side wall extending in a long axis direction of the vibration motor and a second side wall extending in a short axis direction of the vibration motor. The coil is disposed inclined to the first side wall. The vibration motor provided by the present disclosure can simultaneously provide driving forces in two directions of X and Y, achieves dual-f0 vibration output, and is simple in structure, so that not only the working band is effectively expanded, but also the vibration effect is enriched.

摘要： A downhole tool includes a housing. A magnet, an inductor, and a piston are positioned within the housing. The piston moves from a first position to a second position in response to a pressure of a fluid in the housing increasing. A distance between the magnet and the inductor varies when the piston moves, thereby causing the inductor to generate power.
