Facilitating healthcare using smartwatches: Smartwatch data acquisition platform

This report details the design and implementation of a subsystem providing a web-based platform for smartwatch data acquisition. A smartwatch application is developed to read out the accelerometer, gyroscope and heart rate sensor on the smartwatch and transmit the sensor data to the platform. A platform is developed to receive the data and store...

The Smart Teddy Project: Design of a data acquisition system to monitor seniors with dementia and detect dangerous situations

The amount of people dealing with dementia is rising globally. The amount of caretakers is, however, not. Therefore, technological aids are needed to support people dealing with dementia and relieve the stress on their caretakers. Current solutions provide tracking of people with dementia. Also, different robots exist that provide people with...

Design and Fabrication of a Measurement Interface for Smart IoT sensors: Graphical User Interface and GPIB Control

This thesis describes the process of creating the Graphical User Interface (GUI) of a reconfigurable test measurement setup for Internet of Things sensors, which is part of the Bachelor Graduation Project in the Electrical Engineering programme of the Delft University of Technology. The GUI is part of the project in which a system is created to...

High precision Analog-to-Digital Conversion: Nuna Sensor System

This thesis is part of the development of a sensor system for measuring currents in the Nuna solar car. A big problem within this system is the processing of incoming sensor data. Therefore, a solution in the form of a sensor-data-processing-unit was proposed, with its primary focus on the analog-to-digital conversion. The converter should not...

Current Sensor with CAN Interface and Capacitive Tire Wear Sensor

This thesis covers the research, design process and testing of a new current sensor for the Nuon Solar Team. Hall effect and magnetoresistive based current sensors are investigated and compared to a shunt resistor<br/>based current sensor. It will become clear that for the needs of the Nuon Solar Team, a shunt resistor based current sensor is...

Sound localization using an array of Acoustic Vector Sensors: Mainstation data processing

In this thesis five different Direction Of Arrival algorithms will be developed for use with Microflown's Acoustic Vector Sensors, which will determine the direction an acoustic signal originates from. These algorithms will run on a main-station that will remotely receive data from an array of AVSs. The performance of these algorithms is...

Non-intrusive patient monitoring to prevent pressure ulcers: Sensor Subgroup: Creating a sensor solution

Pressure ulcers are wounds that arise when a person sits or lays in the same posture for an extended period of time. Starting from the skin and possibly continuing to the bone, tissue slowly decays when the pressure keeps being applied to the same spot. Prevention is the best method of treating the ulcers and it is done by regularly changing...
