N2 - We present an integrated platform with up to 200 bistable, individually controllable, thermally driven microactuators, that can be used as valves or pumps. In our setup the electronic control layer is completely separated from the fluidic actuators. This allows higher integration then achieved using commercially available surface mounted devices (SMD). The three-dimensional heating structure of our tubular actuators ensures optimum heat transfer, which significantly reduces the switching times. Using a demonstrator with six actuators we applied such actuators as microfluidic valves. The platform may also be used for various other applications such as micropipettes, micropumps and refreshable Braille displays.
