Composite fibers with dynamic and static sensing functions based on a thermal shrinkage process and a rapid preparation method relate to the technical field of composite fibers with core-shell structures. The composite fibers have a core-shell structure including a fiber core layer, a piezoresistive layer, a second conductive layer, a piezoelectric layer, a first conductive layer and an insulating protection layer from inside to outside in sequence, or a metal core layer, the piezoelectric layer, the first conductive layer, the piezoresistive layer and the insulating protection layer from inside to outside in sequence; a coaxial multi-layer functional structure is composited, which integrates the dynamic (piezoelectric effect) and static (piezoresistive effect) sensing functions in a single fiber, thereby breaking through the sensing limitation of a traditional single material or a single physical effect fiber, and realizing synchronous detection of broadband (dynamic and static) force and motion signals.
