Labaar, Derek (author)High-precision systems often comprise many individual systems, each operating at its own frequency. However, the vibrations from one system can be transmitted to another, which yields a response. In high-tech applications where precision is crucial, such as compliant transmission systems, these responses are undesired as they result in a loss in...master thesis 2024

den Daas, Michiel (author)Path generation mechanisms are those mechanisms that produce a predetermined path. Such mechanisms are prevalent in daily life, and many devices depend on path generation mechanisms or are derived from path generation mechanisms. One might think of examples such as vehicle suspension, film advance mechanisms or sewing machines. These are...master thesis 2024

Chen, Qianyi (author), Schott, D.L. (author), Jovanova, J. (author)Soft grippers show adaptability and flexibility in grasping irregularly shaped and fragile objects. However, the low loading capacity and less deformation limit the soft gripper for developing large-scale applications. To overcome these limitations, we propose a new concept of a soft actuator with engineered smart particles. The proposed soft...journal article 2024

Hargrove, Brianne (author), Frecker, Mary (author), Nastevska, Angela (author), Jovanova, J. (author)While nonlinear-elastic materials demonstrate potential in enhancing the performance of compliant mechanisms, their behavior still needs to be captured in a generalized mechanical model. To inform new designs and functionality of compliant mechanisms, a better understanding of nonlinear-elastic materials is necessary and, in particular, their...journal article 2024

Amoozandeh, A. (author), Herder, J.L. (author), Radaelli, G. (author)Compliant mechanisms have the potential to be utilized in numerous applications where the use of conventional mechanisms is unfeasible. These mechanisms have inherent stiffness in their range of motion as they gain their mobility from elastic deformations of elements. In most systems, however, complete control over the elasticity is desired....journal article 2024
