  • Metal wear detection apparatus and method employing microfluidic electronic device
    Patent number: 8522604
    Abstract: An apparatus and a method for detection of wear particles in a lubricant are disclosed. The apparatus includes a microfluidic device including a microchannel sized for a lubricant containing wear particles to pass therethrough and first and second electrodes extending into the microchannel. A detection system is coupled with the electrodes for detection of wear particles passing through the microchannel, based on a change in capacitance of the electrodes.
    Type: Grant
    Filed: October 30, 2009
    Date of Patent: September 3, 2013
    Assignee: The University of Akron
    Inventors: Jiang Zhe, Li Du, Joan E. Carletta, Robert J. Veillette
