1. Redesign of a Printed Circuit Board for a Battery Management System
Master-uppsats, Lunds universitet/ProduktionsekonomiSammanfattning : The ever-increasing interest in electrical vehicles around the world creates a strong developing curve for demand for batteries in electrical vehicles. Meaning, the batteries needs to be able to function better and for a longer time without being destroyed in the process. LÄS MER
2. Application demonstrator for green IoT unit including Ligna S-power
Master-uppsats, Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakultetenSammanfattning : Ligna Energy has developed a printable battery, called S-Power. It is based on research in organic electronics. In order to demonstrate the functionality of the new batteries, an IoT device was developed. The demonstrator consisted of a Sensor for temperature and relative humidity (RH), LoRWAN communication and a circuit for energy harvesting. LÄS MER
3. Antenna as a sensor for sensing available LTE networks
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : This thesis primarily deals with the concept of designing an antenna based device to harvest energy from Radio Frequency (RF) and using the harvested energy to sense the available Long Term Evolution (LTE) network in order for the Internet of Things (IoT) devices to connect to the network for the purpose of transmitting and receiving data. Secondarily the importance of this project is targeting how to conserve battery power in an IoT device and extend it’s lifetime. LÄS MER
4. Current measurements of low-power battery driven devices
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och systemSammanfattning : A current meter has been designed, intended for surveillance of low-power battery driven devices with a large dynamic range in their current consumption. Among such devices may, for example, be nodes in a wireless sensor network (WSN). LÄS MER
5. Design and construction of a portable wireless module
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Institutionen för elektroteknikSammanfattning : In this thesis, a wireless module in form of a portable peripheral printed circuit board that can connect to a master device, periodically sending values from a sensor, has been developed to the company Biotage. A literature study has been made on antennas and PCB-design for high frequency applications and a prototype has been designed through CAD software. LÄS MER
