Profile
The technology was conceived at the University of Wisconsin-Madison lab for advanced materials for energy and electronics under the direction of Professor Michael Arnold. The impact of nanomaterials on society has often been limited because it is difficult to synthesize, purity, process, organize, and integrate nanomaterials and nanostructures. Our research especially draws from multiple disciplines to address fundamental materials challenges - in controlling the growth, processing, ordering, and heterogeneity of nanomaterials and in understanding phenomena beyond the scale of single nanostructures - that must be overcome to exploit these exciting components in technology.

Xolve's graphene technology to change composite price/performance
Nanotechnology has long offered the promise of wonderful new materials and vast improvements in the essentials of modern life. To date, however, this technology has been accused of falling short of such potential. In spite of billions invested in nanomaterials research, no life-changing nano products have made their way to market.20 Feb 2013

The first all-carbon photovoltaic cell
The carbon-based cell is most effective at capturing sunlight in the near-infrared region. Because the material is transparent to visible light, such cells could be overlaid on conventional solar cells, creating a tandem device that could harness most of the energy of sunlight.19 Apr 2012
UWM discovery advances graphene-based electronics
Graphene, a one-atom-thick layer of carbon that resembles a flat sheet of chicken wire at nanoscale, has the potential to revolutionize electronics because it conducts electricity much better than the gold and copper wires used in current devices.2011

Giant piezoelectric effect to improve energy harvesting devices
Researchers in the Department of Materials Science and Engineering and the Materials Research Institute at Penn State are part of a multidisciplinary team of researchers from universities and national laboratories across the U.S. who have fabricated piezoelectric thin films with record-setting properties.25 Nov 2011
Microfabrication breakthrough for piezoelectric material
Integrating a complex, single-crystal material with "giant" piezoelectric properties onto silicon, University of Wisconsin-Madison engineers and physicists can fabricate low-voltage, near-nanoscale electromechanical devices that could lead to improvements in high-resolution 3-D imaging, signal processing, communications, energy harvesting, sensing, and actuators for nanopositioning devices, among others.3 Oct 2011
Harvesting energy from respiration
In a recent paper US scientists from the University of Wisconsin-Madison described a device that converts air flow from human breath into electricity.26 Aug 2011
Reverse electrowetting could lead to energy harvesting shoes
If the vision of Tom Krupenkin and J. Ashley Taylor comes to fruition, one day soon your cellphone - or just about any other portable electronic device - could be powered by simply taking a walk.2010
