In another example, when a pedestrian is walking at night where the light in the surrounding area is inadequate, there is a higher probability of traffic accidents. Because of this, pedestrians often need to equip with reflective devices or self-luminous devices to increase their visibility at night. Moreover, because the self-luminous devices need to be carried everywhere, thin-type batteries are usually set inside the devices. However, the thin-type batteries mentioned above usually contain mercury, which easily causes pollution to the environment.

When returning to its original position, an induced voltage can also be generated, wherein the width of the pulse of the induced voltage is about 88 ms and the peak value of the induced voltage is about 3 volts. Naturally, if the spring return force is larger, the width of the pulse will be shorter and the peak value will be higher.
