IoT

IoT (Internet of Things) and M2M (Machine to Machine) primarily focus on embedded systems. That is computing and communication facilities integrated on a device, example a household appliance, heating or aircon system etc. This allows for automation, as when all household devices,appliances are connected to the internet there functions could be auto controlled from another device connected to the internet. Example a refrigerator could inventory the status of the groceries (in the refrigerator) and auto order to the local grocery store or send you a list of the required items, also you could verify the status of the groceries in the refrigerator at any time.


IoT is gaining popularity in the Smart Grid, Online Security Services and Retail domains, the embedded systems communicate directly with the computers and thus do not require humans to initiate or control any communications.



Energy Harvesting

Any embedded system requires some amount to power to function and if not directly connected to electricity grid, will run out of battery power in sometime. The embedded device can be designed to extract energy from the surrounding environment, any action which generates power (even minuscule amount)  the embedded system should be able to harness and store. If such a system becomes available than the embedded system could function w/o any requirement of battery or any external power.
