Compact design of a planar compliant XY precision positioning stage: For automated malaria diagnosis using a microscope

Malaria remains a major burden on global health, with roughly 200 million reported cases worldwide and more than 400,000 deaths per year. According to the World Health Organization, ninety-three percent of all deaths due to the disease occurred in developing countries in sub-Saharan Africa. This large percentage is directly correlated to the...

Cryo Sample Transfer Solution of Correlated Light and Electron Microscopy

The Nobel Prize in Chemistry in 2017 went to the development of cryo-electron microscopy, which contributed to the discovery of new cells and viruses, the diagnosis of unknown diseases, the mapping of human genomes and the manufacturing of semiconductors. Cryo Correlative light and electron microscopy (Cryo-CLEM), is the combination of using...

The Design of a Compact Angular Drilling Device for Medical Application

The technology used in health care is one of the fastest developing fields in Precision Engineering. The main focus in this field is on the development of steerable, small dimensioned instruments. Using these, surgeries can be done with minimal damage to the patient, shorter hospital stay and more aesthetical healing.<br/>From the medical field...

A new approach to print head movement: Proof of concept for linear motor positioning in an Ultimaker 3D printer

To push the performance of the next generation Ultimaker 3D printers further, a new positioning system is required to improve the printing speed, print accuracy and print repeatability. The expectation is that a linear motor positioning system will perform significantly better than a conventional belt driven system. For this reason, the aim of...

Philips is a giant in the consumer lifestyle goods and prides itself over the quality of equipment produced. Hair clippers are one of the more popular products manufactured by Philips and the hair clipper division of Philips focuses on innovation to maintain the popularity. This time, the idea was to make a resonant hair clipper which can...

Tunable Magnets: Modeling and Validation for Dynamic and Precision Applications

Actuator self-heating limits achievable force and can cause unwanted structural deformations that adversely affect the accuracy in precision actuation systems. This is especially apparent in quasi-static applications that require the actuator to maintain a stable position over an extended period. As a solution, we propose the use of Tunable...

Sensor Calibrations with the Improved Picodrift Interferometer

To meet the growing demand for high precision measurement equipment, sensors with sub-nanometer resolution are becoming readily available. Because of its high precision, traceability and ease of use, the interferometer stands out for high precision measurements. However, the laser beam of an interferometer can be influenced by temperature and...
