A Toyohashi Tech researcher, in cooperation with researchers at Duke University, has invented a production method for oxidation-resistant copper alloy nanoparticles for printed electronics. These novel nanoparticles were produced by an environmentally friendly and economical ‘wire explosion’ method. This invention will expand the application range of printed electronics. “Printed electronics” has the potential to enable […]
A New Measure for Wireless Power Transfer
Wireless power transfer has many promising applications, such as contactless powering, electric vehicles, and energy harvesting. To construct a wireless power-transfer system, a “wireless transfer coupler” is necessary to deliver the energy from a high-frequency power source to a load, with no physical contact. In the past, “coupling coefficient k” was used as an index […]
Super-Small Needle Tech for the Brain
Microscale needle-electrode array technology has enhanced brain science and engineering applications, such as electrophysiological studies, drug and chemical delivery systems, and optogenetics. However, one challenge is reducing the tissue/neuron damage associated with needle penetration, particularly for chronic insert experiment and future medical applications. A solution strategy is to use microscale-diameter needles (e.g., < 5 μm) […]
