The Internet of Things is a promising vision which enables trillions of sensor devices to be connected. A common bottleneck for such devices is the energy supply. Using batteries is expensive, it reduces the device lifetime and has a negative impact on the environment. Energy harvesting provides a more sustainable solution. Unfortunately,...

Machine Learning models are increasingly used to assist or replace humans in a variety of decision-making domains. However, a lot of concerns have been raised about the impact of these decisions on people’s lives. In this work we focus on two main problems. The first one is that there might be discrimination between different groups of people...

RFID technology is slowly replacing traditional bar codes as a way to identify and track objects and individuals. However, consumer-oriented market penetration has been limited as dedicated RFID readers carry a high start-up cost. Furthermore, interactions with individual tags require special-purpose RFID readers. We present a novel RFID tag...

Tiny batteryless sensing systems that do not have a constant supply of power have become an increasingly appealing way to gather data, in hard to reach places, at low cost. These systems suffer from frequent and unpredictable power loss. Preserving information through power failures is an ancillary challenge. Unfortunately, state-of-the-art...

Current hospital protocols dictate patients be turned at least every three hours in the effort of preventing pressure ulcers. To reduce the workload of nurses, Momo Medical has created an embedded sensing device to track the patient's posture and notify nurses when it is time to turn them. The challenge presented and the focus of this thesis is...

Batteryless network nodes could enable unprecedented ubiquitous sensing applications, while gathering energy from the environment and hence removing maintenance costs for batteries. However, these devices inherently suffer frequent power failures and reboots, due to the volatility of the incoming energy, thus classical synchronous message...

Energy harvesting and battery-free sensing devices show great promise for revolutionizing computing in every known area while expanding to non-conventional use-cases. The promise of cheap, dense, and ubiquitous sensing technology brings new applications for the Internet of Things. However, the future programming model is blurry and complex. With...

Progress has been made recently in the research of equal hierarchy backscatter communications. There are, however, challenges to overcome before this technology can become mainstream. For example, state-of-the-art solutions to the phase cancellation problem that occurs in such networks are still trivial and sub-optimal, especially in terms of...

A lot of research is been being done on Visible Light Communication (VLC), which has shown to be of interest for many applications, such as localization. Since localization based on VLC requires active modulation of light sources, this limits the amount of light sources that can be used for localization. Furthermore, in some situations there...

This thesis tries to match the rectifier block of an RF energy harvester to a specific frequency. This specific frequency has the most power and is searched and selected by a smart algorithm. <br/>The algorithm tunes a varactor by applying a proper voltage to set it on different channels.<br/>Then the best channel is sampled and compared with...
