Event details
The
Centre for Internet of Things and Pervasive Systems is organising a seminar titled "Energy Driven Design of Self-Powered IoT Devices: Applications in Cycling Performance Monitoring" from Samuel Wong, a fourth year undergraduate student in ECS. The event is open to anyone from across the University to attend.
The Energy Driven Paradigm is an approach to designing energy harvesting devices where explicit consideration is given to the energy supply and demand characteristics of the application at the very beginning of the development cycle. Instead of designing an IoT device and then optimizing for battery life, or using energy harvesting to extend battery life, what if we start from the harvester and design a system tailored to the harvester. This paradigm shift introduces some interesting challenges, for example the need to have sustained computation spanning intermittent power outages and to have energy aware devices which can respond dynamically to energy scarcity or abundance. Two IoT devices with dramatically different energy harvester characteristics are presented as a case study into the energy driven design process, which were researched through my undergraduate PIII project and summer research internship in ECS. The first device is a wind and inclination meter powered from a tiny wind turbine which gives a low but steady AC power, whereas the second is speed and distance meter powered from periodic pulses of energy. Both devices have wireless connectivity and are battery-less.
