21. Optical measurements in brain tissue during radio frequency lesioning
Sammanfattning : Radio frequency (RF) lesioning is a well well-known procedure within the field of stereotactic neurosurgery, commonly used for the treatment of movement disorders. During the intervention, an RF-electrode is inserted into the deeper parts of the brain, where a small volume of malfunctioning brain tissue will be coagulated. LÄS MER
22. Thermocoagulation in Deep Brain Structures : Modelling, simulation and experimental study of radio-frequency lesioning
Sammanfattning : Radio-frequency (RF) lesioning is a method utilising high frequency currents for thermal coagulation of pathological tissue or signal pathways. The current is delivered from an electrode with a temperature sensor, permitting control of the current at a desired target temperature. In the brain RF-lesioning can e.g. LÄS MER
23. RF Energy Harvesting for Zero-Energy Devices and Reconfigurable Intelligent Surfaces
Sammanfattning : The growth of Internet of Things (IoT) networks has made battery replacement in IoT devices increasingly challenging. This issue is particularly pronounced in scenarios with a large number of IoT devices, in locations where IoT devices are difficult to access, or when frequent replacement is necessary. LÄS MER
24. High-Temperature Radio Circuits in Silicon Carbide Bipolar Technology
Sammanfattning : High-temperature electronics find many niche applications in downhole drilling, aviation, automotive and future exploration of inner planets like Venus and Mercury. Past studies have shown the potential of silicon carbide (SiC) electronics for catering these extreme temperature applications. LÄS MER
25. Ultra Wideband Impulse Radio for Wireless Sensing and Identification
Sammanfattning : Ubiquitous computing and Internet-of-Things (IoT) implies an untapped opportunity in the realm of information and communication technology, in which a large number of micro-devices with communication and/or computing capabilities, provides connectivity for anything, by anyone at anytime and anywhere. Especially, these devices can be equipped with sensors and actuators that interact with our living environment. LÄS MER
