Energy Harvesting


StroNGER forStructures of the Next Generation – Energy harvesting and Resilience

Energy Harvesting (EH) can be defined as the sum of all those processes that allow to capture the freely available energy in the environment and convert it in (electric) energy that can be used or stored.

Applications for the energy sustainabilityEH in buildings – a premise

10

• EH devices are used for powering remote monitoring sensors (e.g. temperature sensors, air quality sensors), also those placed inside heating, ventilation, and air conditioning (HVAC) ducts.

• These sensors are very important for the minimization of energy consumption in large buildings

Applications for the energy sustainabilityEnergy Harvesting for monitoring HVACs operating conditions

Currently:

•Power is provided by batteries or EH devices based on thermal or RF methods

•Sensors work intermittently (to consume less power ~ 100µW)

An EH sensor based on piezoelectric material has several advantages being capable to provide up to 10-15 times more power than currently used devices leading to additional applications or

longer operation time.
