Energy harvesting is the use of ambient energy to provide electricity for small and or mobile equipment, whether electrical or electronic. In 2011, $700 million is spent on the energy harvesting component itself, rising to just under $5 billion in 2021.

Those designing electric vehicles have much in common, whether they are hybrid or pure electric, on-road, off-road, on-water, underwater or in the sky.

Less than two weeks remain until the IDTechEx Energy Harvesting & Storage conference and exhibition and already exhibitors are prepared to demonstrate their capabilities and technology advances, and not just on paper.

Zero power wireless sensors are now available, which bring together new low power wireless ICs with energy harvesters (which harvest energy from heat, light or motion, for example) and the appropriate form of energy storage and conditioning.

In this article we share some of our research for the new IDTechEx report, Electric Motors for Electric Vehicles 2012-2022.

Graphene is considered a hot candidate for applications such as computers, displays, photovoltaics, and flexible electronics.

IDTechEx, the organiser of the World's largest global series of Printed Electronics events will hold its European show in Berlin, Germany on 3-4 April. The focus, as at all IDTechEx events, is to address the needs and experiences of adopters of the technology.

Over the next decade, the most vibrant Wireless Power Transmission (WPT) markets will be the contactless charging of portable and mobile equipment, in particular consumer electronics and electric vehicles.

This year, the world's largest event on printed electronics, "printed Electronics USA" will reflect the widening government support for printed electronics. Beyond the burgeoning programs at universities and government research centers, this is particularly evident in military and electric vehicle work. The US Army reflects this in two presentations. One is an overview of materials printing capabilities and prototype development for US Army applications and the other concerns direct write approaches to nanoscale electronics.

According to IDTechEx research in the new report Wireless Sensor Networks 2011-2021, WSN will grow rapidly from $0.45 billion in 2011 to $2 billion in 2021.

In 2011, IDTechEx research finds that the amount of money spent on energy harvesters will be $0.7Bn, with several hundred developers involved throughout the value chain.

Fuel cells were originally considered to be replacements for internal combustion engines used in traditional vehicles and replacements for traction batteries used in pure electric vehicles.

Led by the Japanese and with Hyundai of Korea, the Europeans and the Americans coming up fast, we are in the decade of the hybrid vehicle, with much more being spent on them than on pure electric vehicles. This is because traction batteries alone cannot affordably provide sufficient range in most of the large applications by land, sea or air.

This article shares some of the research in the new IDTechEx report, {{Range Extenders for Electric Vehicles | http://www.idtechex.com/research/reports/range-extenders-for-electric-vehicles-2011-2021-000276.asp}}. We are in the age of the hybrid electric vehicle which is strongly outselling the pure electric vehicle in market value though not in numbers over the next decade.

The judges noted very innovative and impressive features with real benefits for electric vehicles.

IDTechEx began exploring energy harvesting for small devices four years ago when it was obvious that conventional batteries were a dead end for many wireless sensor applications.

In April 2011, it was announced that Sweden will test the world's first fast rechargeable hybrid bus in Umeå City with a pantograph-based fast charging station, Bůsbaar, developed by Opbrid Transporte Sostenible S.L. It will be a Volvo 7700 diesel converted to hybrid.

Over twenty million electric vehicles produced in 2010 will employ on-board energy harvesting to help charge the traction batteries. That includes both hybrid and pure electric vehicles.

Energy harvesters enabling micro-power generation provide new levels of efficiency and automation in the built environment, process control, vehicles and healthcare.

There are now other forms of energy harvesters developed initially at the micro level which are now being scaled to produce enough energy to replace or supplement grid power.
