Final Thesis
An electronic test circuit for electroactive polymer actuator. The aim of this circuit is to test the possibility of controlling the polymer actuator with a microcontroller (Arduino). The circuit consits of 3 blocks 1) Variable power supply – provides stable voltage 0-12V and current of 125 mA for the high voltage converter. 2) High voltage [...]
Mechanism for prestretching the VHB films. Film is being applied to the mechanism, stretched in each direction and then fixed to the stable frame.
Preliminary sketches on topic of electroactive polymers research and their possibilities of creating interactive behaviour.
Electroactive polymers (EAP) when stimulated by an electric field, these polymers exhibit a change in size and shape. Can be used as actuators or sensors. Diaelectric elastomers are material systems producing large strains. They transform electric energy into mechanical. These capacitors consist of elastomer film sandwiched between two compliant electrodes. When voltage is applied the electrode squeeze the [...]
