Engineering the Comfort-of-Wear for Next Generation Wearables

Wearable technologies are becoming important for the fields of information technology and healthcare, driven mainly by societal issues such as the aging society and the current pandemic. Recently developed flexible/stretchable wearable devices have demonstrated their ability for long-term healthcare monitoring with improved signal integrity and...

Efficiency of three cooling methods for hyperthermic military personnel linked to water availability

Purpose: Three feasible cooling methods for treatment of hyperthermic individuals in the military, that differed considerably in water volume needed (none to ~80 L), were evaluated. Methods: Ten male soldiers were cooled following exercise-induced hyperthermia (rectal temperature (Tre) ∼39.5 °C) using ventilation by fanning (1.7 m s−1),...

The effect of control strategies for an active back-support exoskeleton on spine loading and kinematics during lifting

With mechanical loading as the main risk factor for LBP, exoskeletons (EXO)are designed to reduce the load on the back by taking over part of the moment normally generated by back muscles. The present study investigated the effect of an active exoskeleton, controlled using three different control modes (INCLINATION, EMG & HYBRID), on spinal...

Numerical prediction of car tire wear

Due to their many economic and ecological implications, the possibility to predict tire wear is of major importance to tire manufacturers, fleet owners and governments. Based on these observations, in 2000, a three-year project named TROWS (Tire and Road Wear and Slip assessment was started. One of the TROWS objectives is to provide a tool able...

Advanced optical delay line demonstrator

TNO TPD, in cooperation with Micromega-Dynamics and Dutch Space, has designed an advanced Optical Delay Line (ODL) for use in future ground based and space interferometry missions. The work is performed under NIVR contract in preparation for GENIE and DARWIN. Using the ESO PRIMA DDL requirements as a baseline, the delay line can be used for...

Tyre and road wear prediction

Both tyre wear and road polishing are complex phenomenon, which are obviously strongly related; the energy that polishes the road is the energy that wears the tyre. The both depend non-linearly on numerous parameters, like materials used, vehicle and road usage, environmental conditions (i.e. temperature) and many others. Based on these...
