Every energy source is energy harvesting at some level (even oil, gas, hydro, coal, geothermal, wind, and solar). It seems to me that the emerging Energy Harvesting Market should exclude those sources in the market analysis and only include the harvesting of "incidental" energy (vibration, local temperature gradients, ambient radio waves). Otherwise the statistics will be "double dipping" energy sources.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
