A triboelectric generation apparatus based on a friction brake and a friction brake provide a simple structure with high reliability, a stable circuit, and high energy recovery efficiency. The triboelectric generation apparatus includes two sensing electrodes arranged in a first friction component of the friction brake. When the first friction component is in frictional contact with a second friction component, induced electric charges are generated on the two sensing electrodes. The induced electric charges are different. An electric charge collection circuit is connected to the sensing electrodes and is configured to store the induced electric charges. Storing the induced electric charges allows for the recovery of energy using a simple structure with high reliability.
