I mentioned: "...there should have been a technology such that the display of the mobile device (or a transparent screen on it...the screen protector itself) to be able to harvest electrical energy from the solar energy to charge the battery of the device, so that my mobile will get charged on the way to my office..."
Hope to see a product around this idea sooner than I expected!!! But, did they stole my idea?.... LOL
Btw...what is the time taken by the super-cap to get completely charged with solar touch scree (patented by Apple)and how long the supercap would hold the charge on typical phone usage?
You are right now, since its only 1/10th the density of Li-ion today, but the researchers claim that they could rival NiMH very soon and current Li-ion in just a few years. Of course, Li-ion will have moved on by then to even higher densities, and others like Li-air will be on the scene too. Nevertheless for devices that have significantly more volume in their cases than their existing Li-ion battery takes up, building the battery into the case could become the primary power source.
This is an interesting concept, but looks more suited for supplemental power -- extending operating time beyond what the normal lithium ion battery delivers -- rather than the primary energy storage device.
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.
