The Sensor Roller: A Piezoelectric Energy Harvesting Roller in a Bearing for Self-Sustained IoT Sensors

With the high-speed development of the Internet of Things (IoT), powering such a massive number of wireless IoT sensors with chemical batteries become more and more unpractical. To make the IoT sensors self-sustained, Piezoelectric Energy Harvesting (PEH) technology provides an excellent solution to power the devices with a relatively long...

Testing Energy Harvesting Devices Realistic and Repeatable

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,...

Ambient RF Harvesting in Office Environment for IoT Sensor

This report discusses one part of a project consisting of three parts. The goal of the project is to design a battery less sensor powered by RF energy fields present in an office environment. The sensor is able to measure the temperature and is able to communicate wirelessly using a low power communication protocol. In this project the use case...

Low-power processing and communication

This report discusses one part of a project consisting of three parts. The goal of the project is to design a battery less sensor powered by RF energy fields present in an office environment. The sensor is able to measure temperature and is able to communicate wirelessly using a low power communication protocol. In this project the use case of a...
