Title: Smart actuation and sensing system for bio-mechatronic applications

Supervisor: Carlo Menon

Background

Miniaturized robotic systems for bioengineering applications require the development of innovative lightweight and compact actuation and sensing units based on non-conventional technologies. We have recently developed both an innovative actuation and sensing systems. The actuator, which is bioinspired, relies on a hydraulic system and exhibits large deformations even when high external loads are applied. The sensor is based on the use of optical fibers and resistive sensors, which are capable to detect structural bending. The sensor has been conceived to provide feedback in order to ensure smooth motion on the three-dimensional space. Integration of the proposed actuation and sensing systems could lead to a very miniaturized element suitable for being embedded on prostheses, robotic hands, smart catheters, autonomous micro-system for drug delivery, etc.

Research done so far

We have manufactured polymer-based actuators capable to bend up to 120deg. These actuators are miniaturized (about 1-2 cm) and can lift up to 10g. Conductive polymers and optical fibers are embedded to detect deformations.

Research to be performed

Based on the achievements obtained by researchers in MENRVA’s group, a novel actuator will be designed. Such a system should be able to display large bending deformations about two perpendicular axes. Sensors will be embedded during the manufacturing procedure to obtain a smart structure. A controller will be developed to minimize vibrations and maximize actuator’s performance. Research will be performed with the support of graduate students of the lab.

Required skills: Prerequisite: at least 100 credit hours. The ideal candidate would like to contribute in applied research and be willing to work on a mechatronic project. However, students with expertise in at least one of the following areas are invited to apply: (1) electronics; (2) manufacturing; (3) mechanical design; (4) actuation; (5) sensing; (6) control.

Significance: Applications in the medical field are envisioned. This project is in collaboration with medical companies based in BC.

The device will be used in surgical operations, including endoscopy, laryngoscopy, colonoscopy, etc.
