Bones are an integral part of the human body that exhibit piezoelectric properties, meaning that when stress is applied to the bone, the bone produces a current within itself. This is known as the piezoelectric effect. Material that are piezoelectric can similarly exhibit the reverse piezoelectric effect, meaning that when a current is applied, the material compresses on itself. This property h...
