Explore various ways of generating electricity

It is worth noting that magnetoelectricity is sensed in space, that is, any place that is not conductive can be sensed at a distance, but not in water. Piezoelectric induction occurs in the piezoelectric body, but the resulting sound or ultrasonic waves can carry waves through water. Pyroelectric induction is in the ferroelectric body, but the resulting heat wave can be transmitted everywhere. These three kinds of induction with different properties have an extremely wide range of applications, so solid power generation is still in the initial stage of development from principle to application, and has a great future. For example, on other planets such as the moon and Mars, solid-state generators will likely become the main power source.
