Bio-inspired Smart Adhesive for Underwater Applications

In underwater sensor networks, there is often a need to retrieve the sensors for data collection, replacement of power supplies or maintenance. At present, the entire set-up is removed and the sensors are re-attached on land. A bio-inspired smart adhesive that can be repeatedly turned “on” and “off” on command can potentially be used to provide strong, temporary adhesion while facilitating the retrieval of the attached sensors or devices. The goal is to design a smart adhesive that could be repeatedly activated and deactivated by applied electricity for use with underwater sensors to monitor the waters surrounding the Keweenaw peninsula. The unique temperature conditions of the Keweenaw Bay such as long winter freeze and mild summer temperatures further impact the performance of underwater adhesives.

Students will test the adhesives in the laboratory and attempt to establish the feasibility of use in the waters surrounding the KBIC with graduate students. Students will have the opportunity to learn about mussel protein adhesives, catechol chemistry and its application in reversible adhesives for underwater applications. The information obtained by the students will be vital to support the work being carried out by graduate students in Dr. Lee’s laboratory and provide critical information for future use.
