Shock absorber and vehicle

The invention discloses a shock absorber and a vehicle, which comprises a cylinder body used for defining a piston chamber for containing an ionic solution, a piston movably arranged in the piston cavity comprising a microporous membrane and an electrode which are arranged in a stacked mode. The electrode is arranged at a position provided with a flow passage through which the ionic solution passes. The shock absorber is configured to adsorb ions when the electrode is energized to adjust the flow area of the microporous membrane. According to the shock absorber disclosed by the invention, theflow area of the microporous membrane can be changed through the adsorption effect of the electrode on ions in the ion solution, so that the damping force of the shock absorber can be adjusted to adapt to the current running state, accordingly the adjusting mode is simple, and the adjusting effect is good. 本发明公开了种减振器和车辆，所述减振器，包括：缸体，所述缸体限定出活塞腔，所述活塞腔用于容纳离子溶液；活塞，所述活塞可活动地安装于所述活塞腔内，且所述活塞包括层叠设置的微孔膜和电极，所述电极所在的位置具有供所述离子溶液通过的流通通道，
