Shape morphing is a prevalent feature in all living organisms. Incorporating shape-morphing capabilities into engineered scaffolds in the field of tissue engineering by virtue of 4D printing would allow for structures to closely mimic in-vivo conditions, and dynamically interact with changing cellular microenvironments. Engineered scaffolds...

Cerebral oxygen saturation is an important indicator that reflects the oxygen metabolism of the brain tissues in such patients. The utilization of near-infrared spectroscopy (NIRS) enables the identification of the oxygen saturation levels in nearby tissues by analyzing the distinct oxygenation states of hemoglobin-oxyhemoglobin (HbO2) and the...

inPhocal, a startup company specialized in laser marking, developed a novel optical module to make the depth of focus more than 50mm, and wants to replace ink marking by this laser marking system in the production line when marking information on products. Distortion will always happen when marking 2D patterns onto 3D objects with laser, so...

Flying drones have been a well-established field of engineering for many years now. With the wave of bio-inspired design came the idea of flapping wing micro air vehicles (FWMAVs). These drones use flapping wings instead of fixed or rotary wings to generate their lift, giving them the potential for agile movement and application in confined...

When we manipulate objects in our day-to-day life, we perceive information on the object via force feedback that we sense with our sensorimotor system. However, in virtual reality, we lack these forces, which makes it more challenging to interact with the digital world. Wearables, such as hand exoskeletons, can provide force feedback in VR....

Vibrations and disturbances are becoming more of a concern as lightweight, flexible structures in high-tech systems are pushed towards faster speeds and higher precision. Active Vibration Control (AVC) methods have been effectively used to attenuate vibrations and increase the bandwidth of these systems. With the miniaturisation of electronics,...

Fin Ray Effect (FRE) grippers have proven versatile and effective in pick & place automation applications. However, spherical and lateral round objects are still a challenge for the state-of-the-art, as solutions are unstable when placing those objects off-centre from the longitudinal line. Resulting in large and heavy FRE gripper assemblies...

In this thesis, the accuracy and efficiency of Magnetization State (MS) tuning in Tunable Magnet Actuators (TMAs) is investigated. TMAs are developed to improve thermal stability in quasi-static precision actuation applications. First, the operating principles of TMAs and limitations in previous work are discussed respectively. It is found that...

Going beyond naturally occurring materials, Metamaterials exploit a design at the microscale resulting in macroscopic behaviour, to achieve different or even new properties that can have a wide range of applications. By incorporating sensors, actuators and control, Robotic Metamaterials can achieve even more extremely different behaviour such as...

Magnetic Soft (shape memory) Materials (MSM for short) are a form of shape memory hybrid in which the shape change is initiated by magnetic particles embedded in an elastomer matrix. When an external magnetic field is applied, these magnetized particles will align themselves to this magnetic field, straining the elastomer in a specific shape....

To achieve high motion accuracy and repeatability for a variable reluctance tunable magnet actuator that uses linear controllers, this article proposes a novel actuator design that has a linearized force-flux relation. Prior designed variable reluctance tunable magnet actuators use a C-shaped actuator that has a quadratic relation between the...

In this thesis report, the potential for high-throughput fabrication of micromechanical metamaterials is studied. Metamaterials are structures typically consisting of repetitive micrometre-sized features that introduce new and extraordinary ‘material’ properties. However, up to now these structures are predominantly fabricated with slow 3D-print...

The ever-emerging mobile market induced a blooming interest in stylus-based interactions. However, most state-of-the-art styli are passive or display only unimodal tactile feedback. Multimodal haptic devices that simultaneously stimulate our cutaneous and kinesthetic receptors to provide immersive and realistic sensations in a virtual...

Nature has always had randomness in many ways. Natural cellular structures, specifically, have used randomized microarchitectures to form mechanically efficient materials, such as wood, sponge, and trabecular bone. Mechanical metamaterials are a class of artificial microarchitected materials designed to carry tensions and compressions with...

In high-precision complex mechatronic devices, specifications are mostly affected by the contribution of several disciplines. Thus, in order to facilitate the fulfilment of the specifications, it is crucial to have a well-defined requirement for each sub-system during the entire design process. Model based system engineering (MBSE) is a...

Magnetic soft materials are a newly developed material that can transform into programmed shapes when it is placed in an external magnetic field. It is made out of silicone with embedded magnetic particles that lay in magnetization patterns due to 3D printing them under a magnetic field. Its characteristics are fast, remotely controlled,...

In precision engineering, thermal stability is of great importance in order to keep up with the ever-increasing demand for faster and more precise positioning actuators. Most notably, actuator magnetizing coils dissipate heat to surrounding machine components as a result of Joule heating. With changing temperatures, system components expand and...
