Fraunhofer Institute for Integrated Circuits IISAmbient IoT refers to a new class of wireless communication that is largely self-sufficient by using energy from the environment. It is an ecosystem for connecting and automating a large number of objects and devices, in which each object is connected to form a wireless sensor network using low-cost, self-powered sensor nodes.
As one of the key mechanisms for power supply, Ambient IoT relies on energy harvesting, which eliminates the need for cables to power or recharge batteries in mobile devices and smart objects. Vibrations from equipment, machinery and buildings – or, alternatively, the temperature gradient between pipes, radiators and valves and their immediate surroundings – can be used to generate electricity. Solar cells can also be used for power generation both indoors and outdoors. This electricity can be used to directly power small electronic systems.
