1. Energy Harvesting and Energy Storage for Wireless and Less-Wired Sensors in Harsh Environments
Abstract : Engineering requires sensors to control and understand the environment. This is particularly important in harsh environments. The drawbacks, especially in gas turbines is the complexity of installing a wired sensor and the weight of the wires. This makes wireless sensors attractive. READ MORE

2. Exploiting Energy Awareness in Mobile Communication
Abstract : Although evolving mobile technologies bring millions of users closer to the vision of information anywhere-anytime, device battery depletions hamper the quality of experience to a great extent. The massive explosion of mobile applications with the ensuing data exchange over the cellular infrastructure is not only a blessing to the mobile user, but also has a price in terms of rapid discharge of the device battery.

4. RF Energy Harvesting for Zero-Energy Devices and Reconfigurable Intelligent Surfaces
Abstract : 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. READ MORE
