Researchers at Georgia Institute of Technology have discovered a way to produce electricity from random mechanical motion using triboelectric nanogenerators. These are devices fabricated from flexible polymeric materials with a high degree of transparency. Rubbing the surface of these devices … Continue reading →

Over the years, we’ve seen researchers develop some rather unorthodox energy harvesting systems, including photovoltaics (solar panels), piezoelectric materials that react to motion, and thermoelectrics that turn heat into electricity. Now, MIT Professor of Electrical Engineering Anantha Chandrakasan and MIT … Continue reading →

Radio sensors can monitor installations at locations which are difficult to get to and thus support automation. In these circumstances the energy supply is an important consideration; In order to remove the need for batteries and the associated servicing work, … Continue reading →

The Piezoelectric Playground, a temporary structure designed by Margot Krasojevic for a park in Belgrade, Serbia, was conceived of as both a playground and a bandstand. Whenever agitated by movement and vibration (such as that produced by children playing, or … Continue reading →

A very interesting piece on EE times has been written describing some of the emerging applications for vibrational energy harvesting technologies based on tens to hundreds of microwatts power generation. Take a look at EETimes for the story and more … Continue reading →

Prof. Markys Cain has been interviewed by BBC Click in relation to NPL’s work on Energy Harvesting. Watch the full interview on BBC iPlayer

Professor Keon- Jae Lee’s research team, KAIST (Korea), has developed a nanocomposite-based nanogenerator that successfully overcomes the critical restrictions existed in previous nanogenerators and builds a simple, low-cost, and large-scale self-powered energy system. The team produced a piezoelectric nanocomposite by … Continue reading →

To the long list of exceptional physical properties of graphene, Stanford University engineers have added yet another: Piezoelectricity, the property of some materials to produce an electric charge when bent, squeezed, or twisted. The results were described recently in a … Continue reading →
