Commercialization possibilities of Stirling engine technology for microscale power generation in Sweden (Mechanical Project)
The presented study has evaluated the possibility of commercializing a research project at the Royal Institute of Technologys (KTH) Department of Energy Technology (EGI) in Stockholm, Sweden, where a Stirling engine is used for renewable microscale power generation. The purpose of the study has been to Continue reading
Wireless Power Transmission via Solar Power Satellite (EEE/ECE Project)
A major problem facing Planet Earth is provision of an adequate supply of clean energy. It has been that we face “…three simultaneous challenges — population growth, resource consumption, and environmental degradation — all converging particularly in Continue reading
Low Power Smartdust Receiver with Novel Applications and Improvements of an RF Power Harvesting Circuit (Electronics Project)
Smartdust is the evolution of wireless sensor networks to cubic centimeter dimensions or less. Smartdust systems have advantages in cost, flexibility, and rapid deployment that make them ideal for many Continue reading
Study of Solar/Biogas Hybrid Power Generation (Electronics Project)
This thesis proposes a solar photovoltaic and biogas hybrid system for generation of electricity to overcome from global warming effect, economic and Continue reading
Parasitic Power Harvesting in Shoes (Electronics Project)
As the power requirements for microelectronics continue decreasing, environmental energy sources can begin to replace batteries in certain wearable subsystems. In this spirit, this paper examines three different devices that can be built into a shoe, (where excess energy is readily harvested) and used for generating electrical power “parasitically” while walking.
Two of these are piezoelectric in nature: a unimorph strip made from Continue reading
Piezo-electric Power Scavenging for Mining Applications (ECE/EEE Project)
The growing need of creating a network of sensors in critical environment to monitor, sense and alert an operator about the environment gives rise to the research work carried out in the area of power supply to these sensors.
Wireless sensors are usually designed to run on batteries. However, as the number of sensors increases and the devices decrease in size, there is clearly a need to explore alternatives to battery power for Continue reading
A comparison of power harvesting techniques and related energy storage issues
Power harvesting, energy harvesting, power scavenging, and energy scavenging are four terms commonly used to describe the process of extracting useful electrical energy from other ambient energy sources using special materials called transducers that have the ability to convert one form of energy into anothe Continue reading
Piezoelectric Energy Harvesting Devices for Recharging Batteries
Piezoelectric materials can be used as a means of transforming ambient vibrations into electrical energy that can be stored and used to power other devices. With the recent surge of micro scale devices, piezoelectric power generation can provide a convenient alternative to traditional power sources used to operate certain types of sensors/actuators, telemetry, and MEMS devices.
