Low-Power Gesture Recognition Using Convolutional Neural Networks and Ambient Lighting

This paper presents a study focused on developing an efficient signal processing pipeline and identifying suitable machine learning models for real-time gesture recognition using a testbed consisting of an Arduino Nano 33 BLE and three OPT101 photodiodes. Our research aims to address the challenges of limited computational power whilst...

Smart Personal Protective Equipment: On-Board Power Management

The COVID-19 pandemic caused a shortage of Personal Protective Equipment for Healthcare personnel. This project aims to aid in this shortage by extending the lifetime of the filter material used in a mask. This is done in the form of an SPPE, a Smart Personal Protective Equipment. This face mask has two smart filter heads that are modular and...

The Sensor Patch: Group Energy

The objective of the bachelor graduation project detailed in this thesis is to develop a wireless sensor patch that monitors the health of newborns. The sensor patch replaces the monitoring tasks of nurses during maternity care. The patch measures temperature, heart rate, oxygen saturation and bilirubin. Many babies are born with high bilirubin,...
