1. 1. Feasibility Study of Energy Harvesting via Biofuel Cell for Miniaturised Implantable Biosensors

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Rebecca Bonato; [2024]
   Keywords : Biofuel cell; Blood; Energy Harvesting; Glucose; Power Density; Oxygen;

   Abstract : In the current pursuit of sustainable energy, biofuel cells are attracting considerable attention. Within biomedical engineering, the concept of harnessing energy from biological fluids, such as blood, holds significant promise, enabling both full autonomy and miniaturization. READ MORE

3. 2. Extending energy attack mitigation to multiple IoT devices

   University essay from Uppsala universitet/Datorteknik

   Author : Patrik Johansson; [2023]
   Keywords : ;

   Abstract : A subset of IoT devices in use today rely on energy harvesting technologies for power. This means that rather than being connected to a larger energy grid or using batteries these devices source their energy from their environment, for example by using solar cells. READ MORE

4. 3. mmWave Coverage Extension Using Reconfigurable Intelligent Surfaces in Indoor Dense Spaces

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Zhenyu Li; [2023]
   Keywords : mmWave Communication; Reconfigurable Intelligent Surface; Ray Tracing; Indoor Dense Spaces;

   Abstract : Millimeter-wave (mmWave) is widely investigated for indoor communication scenarios thanks to the available rich spectrum. However, the shortened antenna size and the high frequency make mmWave extra sensitive to blockages. READ MORE

5. 4. Synthesis of Organo-Iron(II) Complexes Including N-Heterocyclic Carbene Ligation as Solar Cell Material.

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Salim Charkas; [2023]
   Keywords : Dye-sensitized solar cell; Transition metal complex; Synthesis iron; N-heterocyclic carbene NHC ; Organic chemistry; Chemistry;

   Abstract : The push-pull design has been shown to increase DSC performance through the introduction of electron-withdrawing groups and electron-donating groups, usually on opposite far ends of the sensitizer. The scope of this thesis was to synthesize several pre-N-heterocyclic carbene ligand analogs that are inspired by the push-pull design in an attempt to investigate their susceptibility to Fe(II) complexation.

6. 5. Extending Wireless Power Transfer Range for Self-Powered Micro Devices with mm-size Antenna

   University essay from Linköpings universitet/Elektroniska Kretsar och System

   Author : Natachai Terawatsakul; [2023]
   Keywords : ;

   Abstract : The primary challenge in expanding the wireless power transfer range for miniaturized self-powered micro devices is the limited RF energy harvesting due to the small effective area and low gain of the mm-sized antennas used in these devices. This thesis introduces a method for extending the distance between an external energy source antenna (TX) and a micro-device antenna (RX) to more than 10 cm. READ MORE
