Energy Harvesting (EH) Technology

Energy harvesting is the process of collecting minute amounts of energy from

the surrounding environment and converting these to electricity. Energy

sources include: light, vibration or heat

Design Wireless (WSN) Problem Engineers fAceWSNs powered with wires or batteries have cost and maintenance

problems

WSNs may require costly electrical wiring

WSN batteries must be replaced periodically, often in hard-to-access places

WSNs powered by solar energy enable the lowest-power Energy

Harvesting Systems, but

WSN placement may limit the size of the WSN, thereby limiting the size and power output of the

solar module

WSN placement may limit the amount of light available, thereby limiting the power available to the

EHS Load and the startup power available for the Energy Harvesting PMIC

WSNs running on EHS-harvested power are difficult to design

They require analog expertise and expensive low-quiescent current1 analog ICs

They require careful design for harvesting, converting and storing energy

Calculating the time-varying EHS Load is complicated

They require flexible low-power ICs to perform the sensing, processing and communicating

functions of the EHS Load
