In 2011 the market for energy harvesters reached US$700 million, with the majority of the value going into consumerelectronic applications, where energy harvesters have been used for some time. Approximately 1.6 million energy harvesters were used in wireless sensors, resulting in $13.75 million being spent on this market segment. The next few years will see a growth in the adoption of energy harvesting for wireless sensors with the market for industrial applications reaching US$140 million by 2017. Wireless sensor networks will be as big as US$200 million with bespoke military/aerospace applications reaching US$210 million (Market data taken from the IDTechEx report “Energy Harvesting and Storage for Electronic Devices 2011-2021”, http://www.IDTechEx.com/energy).
The volume of harvesters (in units) sold into each of the market segments will vary significantly, mainly because of the different size/power output/specifications for each harvester in each market segment. For example, military and aerospace applications will account for approximately 70,000 units of high value harvesters in 2017, whereas industrial applications will reach over 40 million units.
