Passive Temperature-Compensation of MEM Resonators

Rottenberg X., Jansen R., Stoffels S., De Coster J., De Raedt W., De Coster J., De Raedt W., Tilmans H.A.C., IMEC, BE

MEM-resonators are recognized key components for future sensing, wireless and communications applications. Si-based resonators have gained special interest since they offer the perspective to replace bulky quartz resonators on-chip, maintaining high Q-factor and reaching high [...]

High-Stability Numerical Algorithm for the Simulation of Deformable Electrostatic MEMS Devices

Rottenberg X., Nauwelaers B., De Raedt W., Elata D., IMEC, BE

This paper presents a novel high-stability algorithm for the simulation of the electromechanical actuation of electrostatic MEMS devices. Its stability improves on that of voltage- and charge-drive algorithms. It further offers a purely electrical simulation [...]

Functionalized Inorganic Nanostructures for Biomedical Applications

Bonroy K., Jans H., Jans K., Van de Broek B., Van Meerbergen B., Van Summeren A., Jans H., Jans K., Reekmans G., Van de Broek B., Van Meerbergen B., Van Summeren A., Van de Broek B., Van Meerbergen B., Van Summeren A., Huang C., Stakenborg T., Trekker J., Willems M., Bartic C., Verhaegen K., Borghs G., IMEC, BE

Nanomaterials differ significantly from other materials due to two factors: increased surface area and quantumsize effects. These factors can enhance properties such as reactivity, strength and physical characteristics. Due to these characteristics, the coupling of [...]

Modified Nanoparticle Films for Transmission Plasmon Biosensing

Bonroy K., Frederix F., Reekmans G., Jans H., Jans K., Jans H., Jans K., Van de Broek B., De Palma R., Borghs G., IMEC, BE

The principle of the Transmission Plasmon Biosensor is based on LSPR of metal nanoparticles attached to a transparent substrate. When the analyte of interest binds to the bioreceptors immobilized onto these nanoparticles, the absorption properties [...]

Stable Self-Assembled Monolayers for sensitive biosensor interfaces

Jans H., Jans K., Jans H., Jans K., Bonroy K., Frederix F., Reekmans G., Maes G., Borghs G., IMEC, BE

One of the most important requirements for making advanced biosensors and biochips is the attachment of biological receptors onto a solid support. For this reason, it is important to construct a stable and well-characterized interface [...]

Shape-controlled synthesis and functionalization of gold nanoparticles for hyperthermia applications

Van de Broek B., Frederix F., Bonroy K., Jans H., Maes G., Borghs G., IMEC, BE

Control of nanoparticle shape may initially seem like a scientific curiosity, but its goal goes far beyond aesthetic appeal. The shape not only influences the chemical and optical properties of metal nanoparticles, but also their [...]

Lab-on-chip for the isolation and characterization of circulating tumor cells

Laureyn W., Liu C., O’Sullivan C.K., Llaudet E., Nilsson O., Drese K.S., Roeser T., Ritzi M., Hauch S., Albert W., Borgen E., Nygren A.O.H., IMEC, BE

A consortium of 7 European partners has undertaken the challenging task to develop a microfluidic system (μTAS) capable of the isolation/enrichment and consecutive RNA/DNA characterization of circulating tumor cells (CTCs), to be used as a [...]

Simulations of the Anchor Losses in MEM Disk Resonators

Paci D., Stoffels S., Tilmans H.A.C., IMEC, BE

MEM (Micro Electro Mechanical) resonators have been proposed as fundamental components in RF transmission systems; especially bulk mode resonators are very attractive devices because of their small size and their high resonance frequencies combined with [...]

Influence of the Casimir force on the static and dynamic behavior of electrostatically driven micromechanical resonators

Stoffels S., Fernández L.J., Puers R., Tilmans H.A.C., IMEC, BE

Nowadays, electrostatically driven high frequency micromechanical resonators are being developed in which the gap spacing is minimized in order to achieve sufficiently high electromechanical coupling. Typical gap spacings for resonators operated close to a GHz [...]

On Chip Induced Phagocytosis for Improved Neuronal Cell Adhesion

Van Meerbergen B., Raemaekers T., Winters K., Braeken D., Bartic C., Engelborghs Y., Annaert W., Borghs G., IMEC, BE

Efficient integration of neuronal cells and electronic devices could result in hybrid bi-directional communication systems that would enable us to interact at fundamental level with biological structures and get insight in the mechanisms governing their [...]
