Embodiment Construction
[0035] Such as Figure 1-2 As shown, the present invention discloses a vibration energy harvester based on a magnetic phase change alloy. The vibration energy harvester consists of an upper yoke 1, a lower yoke 7, a coil 3, a Heusler type alloy 2, and a MnCoSi-based alloy 6 , iron powder, silicon rubber and permanent magnet 5 are prepared.
[0036]The preparation process of the vibration energy harvester of the present invention is: firstly fix the Heusler type alloy 2 and the MnCoSi-based alloy 6 vertically on the two ends of the lower yoke respectively, and two permanent magnets 5 are then fixed in the middle of the lower yoke; The liquid A and liquid B that make up the silicone rubber are uniformly mixed in the corresponding mass ratio to obtain a liquid, and then iron powder is mixed into it, and the corresponding buffer layer 4 is obtained after natural cooling and solidification, and then bonded to the upper part of the permanent magnet 5, and buffered after curing The ...
