In this talk, we will review the higher groupoid approach towards higher differentiable stacks and introduce shifted symplectic structures on them. We will give some interesting examples and Morita equivalences for them. It is based on several joint works with Miquel Cueca Ten, Florian Dorsch, Leonid Ryvkin and Stefano Ronchi.
