Photonic biosensors for medical diagnostics have been in development for some time. They have proven to show equal or better performance as compared to other techniques in terms of sensitivity, accuracy, and reliability. In order for companies to successfully introduce these sensor products on the market, …

Wearable inertial sensors (WIS) facilitate the preservation of the athlete-environment relationship by allowing measurement outside the laboratory. WIS systems should be validated for team sports movements before they are used in sports performance and injury prevention research. The aim of the present …

We aim to set up a continuous low cost monitoring system for electromagnetic fields in the Netherlands, so that a trend in exposure to 5G signals can be observed. A number of options will be explored for this, such as software-defined radio and measurement nodes for specific 5G frequencies. We developed …

Sensing technology is increasingly used to collect data about the workplace to provide insights into building performance and work activities. While such systems provide meaningful insights, they are a ’black box’ in nature considering people as passive data subjects with no input into the sensing and …

This paper reports on the first stage of a research project1) that aims to incorporate objective measures of physical activity into health and lifestyle surveys. Physical activity is typically measured with questionnaires that are known to have measurement issues, and specifically, overestimate the amount …

In practice, faults in building installations are seldom noticed because automated systems to diagnose such faults are not common use, despite many proposed methods: they are cumbersome to apply and not matching the way of thinking of HVAC engineers. Additionally, fault diagnosis and energy performance …

In wheelchair sports, the use of Inertial Measurement Units (IMUs) has proven to be one of the most accessible ways for ambulatory measurement of wheelchair kinematics. A three-IMU configuration, with one IMU attached to the wheelchair frame and two IMUs on each wheel axle, has previously shown accurate …

In sports, inertial measurement units are often used to measure the orientation of human body segments. A Madgwick (MW) filter can be used to obtain accurate inertial measurement unit (IMU) orientation estimates. This filter combines two different orientation estimates by applying a correction of the …

Royal Eijkelkamp is a company in the Netherlands that specializes in soil improvement, soil conditions, water preservation, and agricultural research. The company has started an innovation platform in partnership with Van Hall Larenstein University of Applied Sciences that is named InnoFields. The InnoFields …

Waterschap Scheldestromen is curious about a 4-electrode conductivity sensor from Interuniversity Microelectronics Centre(imec), which provides a larger working range than Waterschap’s commercial 2-electrode sensor. The project aims to test the performance of this imec sensor, and couple it with Arduino …
