The invention provides a cell manipulation method based on a thin film resonator and a microchip, and the cell manipulation method comprises the steps: arranging a liquid containing cells on a thin film of the thin film resonator, and driving the thin film to vibrate according to a preset resonance mode; and a vortex field is formed in the liquid through film resonance, and the cells are dragged to move towards a stress balance point of the vortex field above an antinode, so that the patterning control of the cells is realized. According to the invention, the resonance mode of the thin film resonator is controlled through the driving frequency of the electric signal to manipulate cells, so that the cell manipulation speed and the cell manipulation precision are improved; meanwhile, an eddy current field is generated through resonance to realize cell manipulation, direct contact with cells is avoided, the original state of the cells can be kept, and unnecessary cell stimulation and damage are avoided; and finally, array manufacturing of the microchip is realized by adopting a micromachining process, parallel manipulation of a large number of cells can be realized, and the cell patterning complexity and manipulation efficiency are improved.
