Abstract
A crank apparatus includes a crank arm having at least one cavity on one of the surfaces of the crank arm, at least one thin material layer embedded within the at least one cavity and having an exposed outer surface, and at least one sensing element attached to the outer surface of the thin material layer. The crank arm is manufactured of a material with non-uniform strain characteristics, the thin material layer is manufactured of a material with uniform strain characteristics, the crank arm is adapted to be deformed by a force, the thin material layer is adapted to be deformed correspondingly with the deformation of the crank arm, the at least one sensing element is adapted to measure the corresponding strain of the thin material layer to measure the force applied on the crank arm. A bicycle and a stationary exercise bicycle equipped with the crank apparatus are further provided.
