The need for wireless charging

I don't find any reason yet why I would need wireless charging for my phone as an user, though I am a great admirer of wireless charging as a technology loving person. This particular method of charging, where the charger pad (or station) needs to be connected to the power socket, looks quite similar to what I do now: I keep my USB charger plugged in to en extender socket on my table and when I need to charge, I just plug the charger to the phone. I don't see a great advantage of switching to wireless charging here, except the very little pain of plugging the USB connector to the phone and more over keeping any eye on the status of the phone battery charge time to time.

How heavy the phone would be, when the battery replaced with the wireless charging kit mentioned in the article? The charging kit comes in the size of a battery?

@Sanjib: This particular method of charging, where the charger pad (or station) needs to be connected to the power socket, looks quite similar to what I do now...

I have a USB charger in my office, but I keep my other one in my backpack -- if I were to leave it out at home, my wife or my 19-year-old son would "borrow" it (and then lose it).

In the case of a wireless charger, even having it plugged in to the wall, I can imagine it being really useful/easy -- just plop your phone down on top of it as you walk by.

In the future, when more and more gadgets are equipped with wireless charging capability, I can imagine the charging station being built in to things like kitchen islands and suchlike.

:) True! Again, in future, will there be more & more gadgets? I was thinking all of these will merge to one or two.

@Max: Max, great article!

@Sanjib: Hi there! Yes, it would be nice if the gadgets merged :-) However, I agree with Max that there could be many more, and believe these different gadgets would emerge from various other areas (i.e. not necessarily limited to smartphones although this would be a huge volume market in the short-term). Some examples of such devices are handheld gadgets for firefighters, medical equipment, diving, wearable sports equipment and other consumer devices such as smartwatches that may have requirements for hermetic sealing, and/or cannot afford to have a USB port opening.

We were at Embedded World in Nuremberg last month, and it's amazing to see several companies approach us (Active-Semi) re wireless power solutions for so many applications that I did not even think of before that! 

I am sure there is a place for the good old' USB connector as you mentioned. But I am also excited about the expected ramp up in these wireless power applications as also echoed by Ryan Sanderson's quote in Max's article :-)

After reading you blog now I came to know that how wireless charging works in order to charge my Nexus 5. I have one wireless charger in my home through which I can simultaneously charge my Nexus 5 and Galaxy S5 on its broad charging pad and another one just installed in my car that I purchased from Amazon http://www.amazon.com/UPGRADED-Universal-Orienting-Windshield-Dashboard/dp/B00F5XPCSC so that I keep my Smartphone's battery full charged while roaming across the countryside. It is right that GPS technology which was not seen in the earlier Smartphone is a part of every device now. And definitely in future wireless charging will also become a part of every Smartphone.

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.
