1. 21. Backscatter Communications for 6G

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Lakshmi Rajeev Cheekati; Jin Yan; [2022]
   Keywords : Technology and Engineering;

   Abstract : The success of future Internet of Things (IoT) depends on, among the other things, developing energy-effcient communication techniques that can enable information exchange among billions of IoT devices with ultra-low/zero power consumption requirements. Ambient backscatter communications is an emerging technology, which utilizes the ambient Radio Frequency (RF) signal as the carrier to reduce the form-factor, and the battery requirements of low-cost small sensor type communication devices.

3. 22. Application demonstrator for green IoT unit including Ligna S-power

   University essay from Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

   Author : Arvid Bläser; [2022]
   Keywords : Ligna; Energy; IoT; Battery; Printed; Electronics; Harvester; LoRa; LoRaWAN;

   Abstract : 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. READ MORE

4. 23. Analysis of radio surveillance in search of missing persons - An empirical study of Bluetooth Low Energy and Wi-Fi characteristics

   University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

   Author : Mikael Fredriksson; [2022]
   Keywords : Search and rescue; Wi-Fi; Bluetooth Low Energy; Wi-Fi probes; Bluetooth Low Energy advertisements; wireless sniffing; smartphones; antenna directivity;

   Abstract : Development of technical and methodological support has been identified as a key area for future research and development within the search and rescue (SAR) of missing persons in Sweden. Previous studies have demonstrated the feasibility of using Wi-Fi signals to locate a missing person, and also developed hardware and software for SAR systems based around Unmanned Aerial Vehicles (UAV).

   Keywords : ;

   Abstract : The Internet of Things (IoT) is expected to enable applications of utmost societal value, such as energy-efficient buildings, smart cities, and next-generation healthcare. While there has been a lot of progress on the security of larger devices, there is a need to consider the security of resource-constrained devices. READ MORE

6. 25. Temperature Dependent Electrical Characterisation of Vertical InAs-InGaAs Nanowire MOSFETs

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Sofie Johannesson; Sebastian Skog; [2022]
   Keywords : Vertical InGaAs Nanowire MOSFET Temperature Dependence Noise; Technology and Engineering;

   Abstract : This thesis presents the temperature dependence of InGaAs Nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs) grown at two different temperatures. The two different growths represent one sample having nanowires which have a mixed crystal structure (showing stacking faults) and one sample with nanowires of pure crystal structure (without stacking faults).
