The possibility to fabricate components in microscopic dimensions opens up new design and application opportunities. Examples of interesting applications where the MICROMUSCLE EAP technology can be incorporated are microfluidics and biological microelectromechanical systems (bioMEMS). Incorporating micromuscles as active components offers considerable advantages in a number of medical microsystem applications.

The controllable volume features of EAP can be used for constructing small valves and seals. Micromuscles exerting force and displacement can also be incorporated into biomedical microsystems where they can perform various tasks, such as lifting, pushing and blocking of micro scale objects.
A microrobot is designed as an "arm" with an "elbow" joint, "wrist", and "hand with three fingers". The robot is 670 µm long and 250 µm wide and can be used to grab micrometer sized objects such as a 100 µm glass bead as shown below.

Micromuscle has constructed small microvials with lids that can be opened and closed using active hinges made of micromuscles. Each vial is 100 µm by 100 µm and 20 µm deep. Inside the vial microelectrodes have been positioned in order to perform impedance measurements on single cells.
