MEMS Mechanism for Fine-tuning Geometric Anti-Spring Compression

The use of geometric anti-springs (GASs) in MEMS accelerometers can not only boost the sensitivity through the static balancing effect, it also introduces the capability to tune the stiffness post-manufacturing by adjusting the balancing force. This paper addresses the challenge of mechanically fine-tuning the stiffness to create the potential...

The Silent Force: Acoustic Trapping in Microfluidics: Exploring the Design and Fabrication of an Acoustofluidic Device for Microbead Trapping and Manipulation

Mechanical forces are integral to the functionality and behavior of biological systems, from the cellular to the molecular level. Acoustic force spectroscopy (AFS), an emerging field, seeks to explore these intricate dynamics. Traditional methods in AFS, particularly those using bulk acoustic wave (BAW) devices, still lack sample visibility and...

Computed Density: Inner city housing using computational design and robotic fabrication

The current demand for living in cities necessitates architectural designers to reflect on how this densification is to be done. Based on analysis of a current densification project in Rotterdam (Rotta Nova) different problems with current densification designs are formulated. From these problems an alternative design for inner city dwellings is...

Fertility detection of chicken eggs in early stage

The worldwide production of poultry meat was estimated to reach 116 million metric tons in 2016. About ten percent of all broiler-type eggs is not fertilized. After the breeding process, these unhatched eggs do not have commercial value and are destined to be destroyed. Moreover, valuable resources are wasted during incubation and the risk of...

Sustainability of the Potato Production Chain: A Thermodynamical Approach

The world economy is expanding. The increasing population is demanding more fresh water and food, more mobility and consumer goods. To fulfil the growing demand without depleting and exhausting natural resources, all food production chains should be sustainable. The most commonly accepted definition of sustainable development, is given by...
