The objective of this thesis is to show that warping can be used in a thin-walled beam to create a suitable replacement for a classical differential mechanism. This normally negated deformation of the cross section can be used to create an inverse transmission mechanism, used to create a monolithic and simple alternative to a classic...

Elastic neutral stability involves elastic deformation without stiffness or loads. It is a remarkable appearance, since the deformation of materials is normally associated with an increase of potential energy and a resulting opposing reaction force or moment. Neutrally stable mechanisms can be used to overcome unnecessary actuation which makes...

Inspired by phenomena in the plant world, a<br/>meteoro-sensitive rotational actuator is developed. The design<br/>uses a hygro-active shell, whose water-based swelling is restricted<br/>at selective locations to form a helicoid structure. The influence<br/>of geometrical parameters on the performance is investigated<br/>using a numerical...

This thesis studies the possibility of energy increase in tape-spring assemblies through stacking, defined as the practice of placing tape-springs on top of each other in parallel. consists of five chapters. Chapter 2 consists of a paper that presents a theoretical approach to stacking of tape-springs, and studies the potential of energy storage...

The mechanisms that move plants can serve as biological role models for engineers, designers and architects. This practice is slowly being implemented in various engineering fields, with architects often being pioneers. Various methodologies have been written about the subject, but often only from an architectural point of view.<br/>The...

Present stroke rehabilitation devices for the arm are often difficult to use by the patient himself and cannot be used at home. A compliant shell mechanism could overcome the shortcomings of the current available devices. By the use of monolithic shell mechanisms a simple to use device can be designed, which can be made wearable. It would make...

Existing scoliosis braces preclude spinal movement for activities of daily living, which reduces the willingness to wear the brace and treatment success. This work develops a scoliosis brace that meets corrective requirements while retaining patient mobility.<br/>The primary compliance vector (PCV) captures the predominant kinematic degree of...

Energy harvesting is the process by which energy is derived from environmental vibrations in order to power local electronic systems . The technology gets rid of the need for electrical wires or batteries in a wide range of sensor and communication networks. This work tackles the three most challenging aspects in the field of vibration energy...
