The study addressesa knowledge gap by offering insights into the circular (re)design for products.The proposed (re)design of the system leads to a substantial reduction of CO2emissions, with...

The effect of recentness of consumer-grade wearable training data on the ability of a DNN to identify users

Heart rate data and other data collected by consumer-grade wearable devices can give away quite useful information about the user. It can for example be used by machine learning algorithms such as Deep Neural Networks (DNN) to learn patterns about cardiovascular disease and fitness, or be used for identification. Heart rate patterns can also...

A study of how outlier detectors can accurately authenticate multiple persons using the heart rate from consumer-grade wearables

The aim of this paper is to complete the gap in the knowledge and experiment using as little as only the heart rate of some subjects to manage to successfully authorise them in some supposed system. The focus will be on the Gaussian Mixture model and the One Class Support Vector Machine, both outlier detectors, because most of the past research...

Analysis and design of a sprung rotational energy harvester for wrist-worn wearables subject to a range of low frequency excitations

A growing energy demand has sparked interest into harvesting energy from the human body. Often, a rotational proof mass is used to harness energy for a wearable from kinetic motion of its user. The addition of a spring has the potential to significantly increase efficiency for these low-power rotational energy harvesters. In this research a...

Using data collected by wearables to improve the efficiency of the routine use of family cars

The experience of using a car can be defined as a lot of things. How comfortable it is to drive in? Or just sit in? What entertainment features does the car have that can keep all passengers entertained for a car journey? Or even for the more extreme motor heads, how does the engine sound when going through a tunnel? All of these factors shape...

From the seashore to the stratosphere: A step closer to continuous lung monitoring using wearable ultrasound: Lung sliding quantification

<b>Background</b>: The prevention of ventilator-induced lung injury (VILI) is an important topic in criticalcare. Lung overdistention is a great attributor to VILI. Regional evaluation of the pulmonary mechanicsis a relatively new method and is currently being studied using electrical impedance tomography (EIT)and computed tomography (CT)....

An ECG- and PPG-Based Wearable Atrial Fibrillation Detection Device: Signal Acquisition

When symptoms of atrial fibrillation (AF), a common cardiac arrhythmia, are experienced, a Holter monitor or event recorder is used for official diagnosis. Apart from the fact that these devices are experienced as inconvenient, AF can already manifest damage in a pre-symptomatic phase. This thesis is aimed at developing a method for recording...

Design and engineering of an energy harvesting system for smart clothing

We live in a society in which we rely heavily on energy. We need it everywhere and made great advancements which allow us to bring energy with us wherever we go; one of these advancements are batteries. In order to be less dependent and generate our energy locally when needed this project focusses on this topic. Creating a design framework which...

Design of a modular system for textile wearables

The thesis clarifies the graduation project for the master program of Integrated Product Design at the Delft University of Technology. It describes an interconnection method to connect electronics onto the smart textiles that differs from any solutions existing in the market. Smart textiles are considered as the future of the clothes and are...

Thermotion: an exploration of facilitating emotion perception with wearable thermal displays

The project aims at exploring tangible ways to communicate emotion. To narrow down the scope, I lay the focus on emotion communication in remote settings, a context when nonverbal communication is usually limited. From interviews, the neutral expression is found to be the main factor hindering a sufficient understanding of others' emotional...

Physical Activity Recognition using Wearable Accelerometers in Controlled and Free-Living Environments

Physical activity recognition through wearables has enabled the development of novel applications in healthcare. Most of the existing studies focus on predicting activities using wearable sensors, either in a controlled or uncontrolled environment. However, there is not a clear distinction between these two environments. Hence, this thesis aimed...

Envision: enabling vision for visually impaired

Envision began as an attempt to increase independence for people with visual impairment. During the course of the project, through a very participatory design approach, a deep understanding of the challenges faced by visually impaired people was obtained. A technology exploration in search for potential solutions led to the discovery of the...
