WSNs are easily integrated into different environments. Low New Route Power Harvesting. Energy Very Low Energy ◦ Avoid the use of physical maintenance. New New Route Route ◦ Increase the life cycle virtually New Route Concentrator forever. Power Harvesting techniques build potentially self-sufficient devices/systems.
Pervasive systems relay in a determined QoS. Not reliable energy source.PH Implications ◦ Can affect the quality of the Pervasive Services. Non deterministic energy source. ◦ Not easily predictable and can not be foreseen. Uncertain quality of services. ◦ Difficult management of the energy resources can lead to service lost or unnecessary quality degradation.

What do current Power Harvesting techniques lack in order to be effectively applied to Pervasive Systems? Will “user dependable” technologies get acceptance into homes?
