Steijlen, A.S.M. (author), Bastemeijer, J. (author), Plaude, L. (author), French, P.J. (author), Bossche, A. (author), Jansen, K.M.B. (author)In elite European football, 6 to 7 hamstring muscle injuries occur per team per season, which results in an absence of 14 to 180 days (Ekstrand et al. 2017). These injuries occur typically in the last part of a training or match. This implies that the accumulation of demanding actions is an important factor for hamstring injury risk. In current...conference paper 2020

Li, X. (author), Jansen, K.M.B. (author), Zhang, X. (author), Rozendaal, M.C. (author), Jonker, C.M. (author)Stress is an important aspect of mental health which impacts on wellbeing. Wearable devices are increasingly used to help people deal with stress in daily life. However, most of the current applications focus on detecting and representing physiological data. In this paper we report on the design of an integrated wearable system composed of...conference paper 2020

(author)Sweat sensor patches offer new opportunities for unobtrusive monitoring of an athlete’s physical status. This paper presents a novel sweat rate and sweat conductivity patch that is easy to prototype and can be made with common low-cost production techniques: laser cutting and standard printed circuit board (PCB) manufacturing. The device...conference paper 2020

(author)A wide variety of electrochemical sweat sensors are recently being developed for real-time monitoring of biomarkers. However, from a physiological perspective, little is known about how sweat biomarkers change over time. This paper presents a method to collect and analyze sweat to identify inter and intraindividual variations of electrolytes...conference paper 2020

(author), Neerincx, M.A. (author), Truong, Khiet P. (author)An important aspect of human emotion perception is the use of contextual information to understand others' feelings even in situations where their behavior is not very expressive or has an emotionally ambiguous meaning. For technology to successfully detect affect, it must mimic this human ability when analyzing audiovisual input. Databases...conference paper 2019

RÖggla, Thomas (author), Li, Jie (author), Fjellsten, Stefan (author), Jansen, Jack (author), Kegel, Ian (author), Pilgrim, Luke (author), Trimby, Martin (author), Williams, Doug (author), Cesar, Pablo (author)While traditional live-broadcasting is typically comprised of a handful of well-defined workflows, these become insufficient when targeting multiple screens and interactive companion devices on the viewer side. In this case study, we describe the development of an end-to-end system enabling immersive and interactive experiences using an...conference paper 2019

For this, we developed a discrete component-based backscatter T2T transceiver and a communication protocol suite. The protocol composed of a novel (i) flooding-based link control tailored towards backscatter transmission, and (ii) low-power listening MAC. The...conference paper 2019

de Zeeuw, W. (author), Jesus de Moraes, R. (author), Heemink, A.W. (author), Jansen, J.D. (author)We propose a novel adaptive, adjoint-based, iterative multiscale finite volume (i-MSFV) method. The method aims to reduce the computational cost of the smoothing stage of the original i-MSFV method by selectively choosing fine-scale sub-domains (or sub-set of primary variables) to solve for. The selection of fine-scale primary variables is...conference paper 2019

Jansen, K.M.B. (author)Smart textiles are textiles with integrated sensors, data processing, communication and power units and can be regarded as a new application field for microelectronic devices. It largely benefits from a series of recent developments: sensors become smaller, more reliable and require less power and, on the other hand, energy harvesting...conference paper 2019

Jansen, B. (author), Hermans, F.F.J. (author)Spreadsheets are frequently used in industry to support critical business decisions. Unfortunately, they also suffer from error-proneness, which sometimes results in costly consequences. Experiments in the field of program education have shown that programmers tend to make fewer errors and can better focus on the logic of a program if they use a...conference paper 2019

Jansen, A.J. (author), Dekker, M.C. (author), van der Steen, Diederik (author)Providing athletes with real-time feedback on their performance is becoming common in many sports, also in speed skating. This research-by-design project aims at finding a tool that allows the speed skater to get real-time feedback on his performance. Speed skaters often mention a so-called “good feeling” when skating behind a better skater. It...conference paper 2018
