Abstract [en]

Within the areas of cell biology, biomedicine and minimal invasive surgery, there is a need for soft and flexible manipulators for handling biological objects, such as single cells and tissues. Polypyrrole (PPy) trilayer actuators are an attracting option since they use low power, are soft and can be operated without the need of an external electrolyte. The PPy trilayer actuator is made of three layers laminated together: two outer two layers of PPy and a middle, insulating layer of polyvinylidene difluoride (PVDF) to separate the two electrodes and contain the electrolyte. To date, only simple, individual actuators as have been fabricated and characterized. For the applications mentioned previously there is a need to be able to also fabricate complex structures, comprising individual addressable microactuators, for instance, in the form of multi-degree of freedom legs and microrobotic grippers.

We have developed different microfabrication and patterning methods for both thick, membrane PVDF- and thin film PVDF-based trilayer actuators, which require different processing steps, thus extendeding our processing capabilities. We will present these new processing methods and initial articulated microactuator devices, i.e. actuators comprising individually controllable actuators/segments.
