A Fraunhofer EMFT research team is working with 19 European partners from industry and research on the EU project ADMONT to develop an integrated high-voltage driver (ASIC) for micropumps. A pilot line of the chip is to be realized in the cleanrooms of X-Fab in Dresden.
The energy efficiency and response time of ASICs are significantly higher than is the case with the discrete type normally used nowadays. This enables pump accuracy to be increased and the electronics to be miniaturized without losing out on performance capacity – a key requirement for promising applications such as in medical implants or smartphones. The long-term project goal is to achieve an overall solution for microdosing systems which allows monitoring and control of the pump. The chip will monitor whether the pump is operating error-free, for instance, or adapt the pump function by means of various selectable program modes.
