Your idea is very innovative, since it turns the display into a solar energy concentrator. The inventors of the quantum-dot window are concentrating on scaling them up so that windows in homes and buildings can also be concentrated solar energy harvesters. Scaling down to mobile device size would require photovoltaic cells that were very thin to fit around the edge of a display, but the concentration factor should be impressive since the entire face of the display would be funneling incident light to the PVs. Only time will tell if your idea is workable, but I see promise.
What would be the application of the Quantum dot enabled solar energy harvesting? The mobile devices would be able to harvest solar energy to generate power sufficient for charging the battery of the mobile devices? Recently while driving to my office I kept my phone on the seat next to mine. Sunlight was falling on its display and I was thinking (or rather wishing) that, 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... :)
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.
