Magnetic Design Challenge: Innovative Locking Mechanism

This lecture presents a mechanical engineering project involving the creation of an all-locking mechanism using Magnetorheological Elastomers (MRE). The mechanism, designed as a credit card-sized key, deforms under an external magnetic field to unlock doors and safes. The process involves designing and molding MRE beams, magnetizing them, and testing their deformation in practice. Challenges faced include tuning the dimensions of the lock and matching the deformation of the key, with potential for further advancements in shape complexity and sensor integration.
