The invention provides a friction power generation device based on a friction
brake and the friction
brake. The friction type
brake comprises a first friction
assembly and a second friction
assembly which are oppositely arranged, when the first friction
assembly generates
contact friction relative to the second friction assembly, friction braking force is generated, and charges are generated; thefriction power generation device comprises a first induction
electrode, a second induction
electrode and a charge acquisition circuit, wherein the first induction
electrode and the second induction electrode are arranged in the first friction assembly, when the first friction assembly generates
contact friction relative to the second friction assembly, first induction charges are generated on thefirst induction electrode, and second induction charges are generated on the second induction electrode; and the charge acquisition circuit is connected with the first induction electrode and the second induction electrode and stores charges acquired from the first induction electrode and the second induction electrode. The friction power generation device is simple in structure, high in reliability, stable in circuit and high in capacity
recovery efficiency.
