This paper proposes that next generation wireless
capsule endoscopy (WCE) technology will feature active me-
chanical components (i.e. actuated) as opposed to current sys-
tems that are predominantly passive (e.g. for imaging purposes).
Future systems will integrate microsystems that use micro-
actuators to, for example, perform micro-surgery, take tissue
samples, deliver medication, etc. In this paper we detail a novel,
ultra-compact integrated mechanism for resisting peristalsis
and describe how this can be fabricated in Nylon 6 using
CNC milling. The holding action is achieved by extending
an “anchor” spanning an effective 60.4 mm circumference, for
a 11.0 mm diameter WCE. This function is achieved by a
mechanism that occupies only 347.0 mm
3
volume, including
mechanics and actuator. This shows how exploiting conventional
manufacturing processes can result in a radical change in the
capabilities of WCE systems and empower the next generation
of active devices.
