Martins Da Ponte, R. (author)
The development of personalized healthcare solutions is a complex and multifaceted challenge that requires synergistic collaboration and cross-fertilization between multiple disciplines, including microelectronics, nanotechnology, materials science, and biotechnology. As numerous biomedical applications necessitate the precise regulation and...

Silicon sensors date back to before 1960 with early Hall and piezoresistive devices. These used simple processing that was part of the early integrated circuit (IC) industry. As the IC industry developed, silicon sensors could benefit from the technological advances. As silicon sensors advanced, there came the need for new technologies...

In-vivo sensors yield valuable medical information by measuring directly on the living tissue of a patient. These devices can be surface or implant devices. Electrical activity in the body, from organs or muscles can be measured using surface electrodes. For short term internal devices, catheters are used. These include cardiac catheter (in...

Self-folding broadly refers to the assembly of 3D structures by bending, curving, and folding without the need for manual or mechanized intervention. Self-folding is scientifically interesting because examples of self-folded structures, from plant leaves to gut villi to cerebral gyri, abound in nature. From an engineering and technological...

An experimental setup to perform dynamic analysis of a micro- and nano-mechanical system in vacuum, gas, and liquid is presented. The setup mainly consists of a piezoelectric excitation part and the chamber that can be either evacuated for vacuum, or filled with gas or water. The design of the piezoelectric actuator was based on a Langevin...

To facilitate research on the dynamics of micro-cantilevers immersed in liquid, a modal test setup was designed. Modal testing is a powerful form of dynamic testing whereby the system's natural frequencies, modal masses, modal damping ratios, mode shapes, and weight of each of these modes at a certain frequency are determined. Micro-cantilever...

In situ stiffness adjustment in microelectromechanical systems is used in a variety of applications such as radio-frequency mechanical filters, energy harvesters, atomic force microscopy, vibration detection sensors. In this review we provide designers with an overview of existing stiffness adjustment methods, their working principle, and...

A sun sensor is usually included in a satellite for optically measuring the position relative to the sun. The accuracy of a conventional sun sensor is affected by reflected sunlight at the nearby earth atmosphere: the albedo radiation. The part of the spectrum at near IR (1.5 ?m) is not included in the albedo radiation, due to the high water...

The assembly of microsystem chips in industrial practices is commonly done by means of a single pick-and-place operation. Despite its high process reliability, this operation is a serial process that cannot compete with the efficiency of the inherent batch-processing capability of the microsystem fabrication. Besides, the speed of a pick-and...

Microsystems are very small sensors and actuators, manufactured with the same technology as computer chips. Well known applications of these machines are the acceleration sensors in the Wii game console and the iPhone. At the micrometer length scales of microsystems the physical forces behave different when compared to devices operating in the...

Henneken, V.A. (author)
In this project, the technical feasibility of a novel assembly concept was explored, in which microsystem-based self-assembly functionality is added to an existing product. The case considered is the accurate alignment of an optical fibre relative to a telecommunication laser source. In the most demanding cases this requires alignment accuracies...
