Power requirements for IoT devices

There is a lot of buzz about the proliferation of the IoT devices and some of the market reasearch gurus are predicting that there would be billions of IoT devices in the next 4-5 years.

 

Thw main question is the power supply to such devices , many of which will be tiny devices and many of them located remotely and workd wirelessly.

 

In my opinion there is a need to go away from the traditional techniques of having a power supply unit with each sensing or controlling device.

 

Instead we need to evole a technique of energy harvetsing such that each of these IoT device will have there own energy source to cater to the power needs of that device.

The energy harvesting on board can be done by conversion of thermal energy, solar energy or any kind of chemical energy .

Agreed, especially with potentially 24 hr wireless activity.

I'm afraid the 2nd law of thermodynamics practically limits the efficiency of direct energy conversion to low values, unless you're converting to heat (instead of electricity).

Could a thermocouple kind of junction produce enough voltage and current to be able to drive a small IoT device?

LATEST ARCHIVED BROADCAST

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. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
