abstract |
The concept of biomimetics and bioinspiration has been used to enhance the function
of materials and devices in fields ranging from healthcare to renewable energy. By
developing advanced design and manufacturing processes, researchers are rapidly accelerating
their ability to mimic natural systems. In this paper we show how micro-actuated forceps
inspired by echinoderm pedicellarie have been produced using the rapid manufacturing
technology of micro-stereolithography. The manufactured monolithic devices are composed
of sets of jaws on the surface of thin polymer resin membranes, which serve as musculature
for the jaws. The membranes are suspended above a pneumatic chamber with the jaws
opened and closed through pneumatic pressure changes exerted by a simple syringe.
The forceps can be used for tasks such as grasping of microparticles. Furthermore,
when an object is placed in the centre of the membrane, the membrane flexes and the
jaws of the device close and grasp the object in a responsive manner. When uncured
liquid photopolymer is used to actuate the devices hydraulically instead of pneumatically,
the devices exhibit self-healing behaviour, sealing the damaged regions and maintaining
hydraulic integrity. The manufactured devices present exciting possibilities in fields
such as micromanipulation and micro-robotics for healthcare. |
