Speaker Biography (Tom Krupenkin)

Tom Krupenkin, Company President, holds professorship appointment at the Nanotechnology Cluster and Mechanical Engineering Department, University of Wisconsin-Madison. He received a Ph.D in materials science from Moscow Institute for Physics and Engineering, Moscow, Russia in 1992, and a Ph.D in physics from Case Western Reserve University, Cleveland, Ohio in 1996. From 1998 to 2007 he was a Member of the Technical Staff at Bell Laboratories, Lucent Technologies. Prior to that, he worked for two years at the Materials Research Laboratory, University of California, Santa Barbara. He holds over 50 US and international patents and has authored over 35 publications. His research is focused on physics and chemistry of nanostructured surfaces, NEMS/MEMS devices, and physics of liquid-solid interfaces. Professor Krupenkin has received numerous professional awards and distinctions including the American Chemical Society Industrial Innovation Award (2007) for his work on tunable nanostructured surfaces; the Excellence in Research Award (2005) and the Energy Storage Enabling Technology of the Year Award (2006) for his work in Nanomembrane Battery; and the Emerging Technologies Award for his work in Microfluidics in Photonics (2003). His research has consistently attracted substantial media attention including articles and news pieces in The New York Times, Scientific American, ABC News, Nature Materials, Physics Today, Science News, and New Scientist.

Company Profile (InStep NanoPower, LLC)

InStep NanoPower, LLC specializes in developing nanotechnology-based solutions for high-power energy harvesting for mobile applications. Powering mobile electronics is a challenge - the short time between battery recharges as well as the lack of adequate electrical power in many geographical areas impose severe restrictions on the development and use of portable electronics. The novel footwear-embedded energy harvester developed by InStep NanoPower captures energy produced by humans during walking, which is normally lost as heat, and converts it into electrical power that can be used to power mobile electronic devices. Unlike a traditional battery, the energy harvester never needs to be recharged, as the new energy is constantly generated during the normal walking process. The energy harvesting technology developed by InStep NanoPower allows our customers to offer a broad range of novel products that can free mobile electronics users from electrical grid dependence, decrease their reliance on electrical batteries and greatly increasing the mobile devices operational time.
