Contactless Inductive Power and Data Transfer: For use in E-Textiles

Distributing power and data around a garment is a common problem in sensor enabled e-textiles, as connecting separate electronic subsystems together using connectors and wires has proven to be unreliable and cumbersome. In this work a solution is presented that will eliminate the connectors by using two pairs of short-range wireless inductive...

Reliable wireless data transfer for smart sensor shorts in football

In football, most of the injuries occur in the lower extremities of the athletes. The leading cause of this is high muscle stress during explosive actions. To be able to prevent injuries, the Dutch Football Association (KNVB) and Dutch Hockey Association (KNHB) are working on smart sensor shorts in collaboration with the Delft University of...

Ionic sweat analysis for health monitoring in real-time exercise

Sweat analysis has the potential to become a new method in the wearable monitoring technology market by providing new and more precise physiological parameters. The need for more accurate sweat sensors has not allowed setting a correlation between sweat constituents and a person's health status. The development of this research field could lead...

Designing a wireless communication system for smart sensor shorts in football: Using lossless data compression and pattern diversity

Decreasing injuries in football is a topic of interest for the KNVB and KNHB. To reach this goal, the use of smart sensor pants is researched. The data will be used to develop models for finding injury risk factors that are related to movements. Currently, the system is capable of reading out the IMUs and storing the data on an SD-card, for post...
