Designing self-tracking experiences: A qualitative study of the perceptions of barriers and facilitators to adopting digital health technology for automatic urine analysis at home

Delphine Ribes Lemay, Nicolas Henchoz, Emily Clare Groves, Margherita Motta, Andrea Regula Schneider

Self-tracking technologies open new doors to previously unimaginable scenarios. The diagnosis of diseases years in advance, or supporting the health of astronauts on missions to Mars are just some of many example applications. During the COVID-19 pandemic, ...

On the debris-level origins of adhesive wear

Jean-François Molinari, Ramin Aghababaei, Derek Warner

Every contacting surface inevitably experiences wear. Predicting the exact amount of material loss due to wear relies on empirical data and cannot be obtained from any physical model. Here, we analyze and quantify wear at the most fundamental level, i.e., ...

Complex event recognition through wearable sensors

Jean-Eudes Marie Ranvier

Complex events are instrumental in understanding advanced behaviours and properties of a system. They can represent more meaningful events as compared to simple events. In this thesis we propose to use wearable sensor signals to detect complex events. Thes ...

Instrumented shoes for activity classification in the elderly

Kamiar Aminian, Anisoara Ionescu, Christopher Moufawad El Achkar

Quantifying daily physical activity in older adults can provide relevant monitoring and diagnostic information about risk of fall and frailty. In this study, we introduce instrumented shoes capable of recording movement and foot loading data unobtrusively ...

Self-Tracking Solar Concentrator Device

Jacques-Edouard Moser, Christophe Moser, Volker Günter Zagolla

A device for self-tracking a light source, including a focusing optical device configured to focus incoming light to a focal spot, an adaptive device configured to reflect the light of the focal spot and arranged to provide for a phase change at an area of ...

Self-tracking Solar Concentration

Volker Günter Zagolla

Solar concentration is intended to decrease the cost of expensive solar cell material by replacing the solar cell with a focusing optical system as the initial receiving aperture. This reduces the amount of solar cell material needed but adds the need of t ...

Self-tracking solar concentrator with an acceptance angle of 32 degrees

Christophe Moser, Eric Tremblay, Volker Günter Zagolla

Solar concentration has the potential to decrease the cost associated with solar cells by replacing the receiving surface aperture with cheaper optics that concentrate light onto a smaller cell aperture. However a mechanical tracker has to be added to the ...
