Abstract
A microinjector head with a driving circuit and the manufacturing method of the microinjector head are shown. The microinjector head uses a bubble as a virtual valve to eject fluid. The microinjector head has a manifold, chambers, a pair of first and second bubble generators, orifices, and a driving circuit. The driving circuit is used to control the pair of first and second bubble generating devices and eject fluid inside the corresponding chamber from the corresponding orifice. In addition, because the driving circuit and the bubble generators are integrated on a single substrate, the number of manufacturing processes is reduced and the circuit devices and connecting circuits of the. microinjector array are fewer.
