The two technologies - the e-paper generator and the contact less charging for EVs are the most interesting as far as I am concerned.
The e-paper generator can make the future newspapers electronic yet fold-able like today's newspapers and that will be an interesting evolution.
The contact less charging of EVs , if it can be done while the vehicle is running on the road ( though the below surface charging wires can be another revolutionary concept that can bring the Evs into the mainstream of automobiles
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. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
