Let M be a spin manifold of even dimensional. In this dissertation, we define a rescaled bundle S over the tangent groupoid $\mathbb{T}M$ which incorporates Getzler's symbol calculus. We prove that this bundle has a multiplicative structure and a continuous family of supertraces. We also define a modified version of the rescaled bundle and apply it to the context of Bismut's hypoelliptic Laplacian on compact Lie group.
