Sensorized roller for a bearing having integrated energy harvesting device

Abstract

A sensorized roller for a bearing includes a bore that extends through the roller, a sensor for measuring at least one physical state of the roller bore and producing a first signal indicative of the measured physical state, a wireless transmitter for receiving the first signal from the sensor and wirelessly transmitting a second signal based on the first signal, and a generator configured to be rotated by a movement of the roller, the generator being electrically connected to the sensor. The measuring unit, the wireless transmitter and the generator are located inside the bore.

Dependencies are inferred from the claim text.
