Wireless Power Harvesters: A Charging Solution for IoT Applications

Speaker: Lei Guo, Dalian University of Technology, China

Abstract

The realization of Internet-of-Things (IoT) relies on a large amount of geographically distributed wireless sensor nodes (WSNs). Traditional power supply cords prevent the large-scale utilization and mobility of the WSNs, while the batteries as substitutes for supply cords are not optimal solutions due to the limited lifetime, high cost, and undesired ecological effects. In this scenario, wireless power harvesting technologies provide a new approach to remotely charging or powering WSNs. This talk will discuss analytical methods for evaluating and designing radio frequency (RF) power harvesters by considering the wide adaptability to frequencies, input power, and load conditions. Based on the analysis, high-efficiency multi-band or wide-power-range RF power harvester systems will be designed and discussed. The feasibility of the proposed RF power harvesters will also be demonstrated in a real low-power wireless sensor platform. The proposed wireless power harvesting techniques have the potentials to be implemented in IoT applications where powering issues are critical.

Semiconductors for GHz to THz Devices

Speaker: Kiki Ikossi, 2020-2022 ASEE Science and Technology Policy Fellow at the National Science Foundation, Alexandria, VA, USA

Abstract

High-performance devices, integrated circuits for future energy-efficient high-speed communication networks, and IoT sensors demand high-performance semiconductor devices that can be integrated into advanced systems. This talk will examine the properties sought for heterostructure devices for GHz to THz applications. Challenges faced by the key high-speed device technologies that set in motion the communication revolution of our times will be discussed, along with some of the efforts underway for fulfilling the demands of future applications. We will see how the presence of defects and carrier traps in semiconductors hinder device performance and affect efficiency and how future technology can exploit these traps.

The Evolution of Surface Radar and Naval Platform Integration

Speaker: Sara Pena Barros, Thales Nederland B.V., The Netherlands

Abstract

Naval forces are exposed to several different threats with elaborate behaviors, especially uncrewed air and surface vehicles, in a complex above-water environment. This translates into a need for superior air and surface detection, tracking, and classification performance. In a high-intensity Above Water Warfare context, the integration of all sensors provides a higher quality and faster tactical picture, giving a clear, rapid full situational awareness (air, surface) and increased defense capabilities of the whole task group. This talk will focus on the hand-in-hand evolution of surface radar with an evergrowing-in-complexity threat scenario and the challenges of naval platform integration of such (multi-) sensor systems.
