...forgot to comment why a toothbrush-type application makes sense. This is an application where the charger functionality is hidden. The toothbrush charger is primarily a storage socket to keep your toothbrush off the counter - and oh by the way it also charges. A portable phone doesn't always sit on the charger pad. You have to go out of your way to put your phone where you normally don't store it.
Another bigger application is a floormat electric car battery charger. Again, you park you car on the garage floor - and oh by the way the mat on the floor couples the charge while you are parked.
Apple has already said they have no plans for wireless charging. And their reasoning is sound: one still needs to plug a charger into the wall.
And as far as a universal charging standard: that already exists. It's called USB and is used by everyone in the business.
If wireless charging makes sense, it will be in applications that are similar to a toothbrush - a charging solution that's been around for more than one decade.
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.
