Patent number: 10386249Abstract: A wearable inductive-force sensor, which provides high-sensitivity dynamic measurements of both normal force and shear force, utilizes three spiral planar force sensing coils. These spiral planar coils allow the measurement of shear force in the x and y directions and the measurement of a normal force in the z direction. The force sensor is configured to be mounted in various locations, such as an insole of a shoe, so as to provide real-time force sensing of forces that are applied to a patient's feet as they move. In addition, force-measurement electronics used with the force sensor are configured to use resonance-frequency division signal multiplexing to monitor the response of the force sensing coils, which allows the sensor to have minimal complexity, while still being highly sensitive.Type: GrantFiled: February 20, 2015Date of Patent: August 20, 2019Assignee: The University of AkronInventors: Jiang Zhe, Li Du

Patent number: 9797851Abstract: An apparatus for detecting wear particles in a fluid includes an inlet channel and an outlet channel. An ultrasonic transducer creating an acoustic wave that defines an acoustic focal zone is located between the inlet and outlet channels. A flow path located between the inlet and outlet channel is shaped to restrict the flow of the fluid to be within the acoustic focal zone. An inductive pulse sensor includes a plurality of flow channels receiving the fluid and a plurality of planar coils wound around the flow channels. The inductive pulse sensor includes a detection system for the detection of wear particles passing through the flow channels based on a change in an electrical property of the planar coils. A single combined excitation signal is sent to all the planar coils at once and the detection system measures one single output measurement for the plurality of flow channels.Type: GrantFiled: November 27, 2013Date of Patent: October 24, 2017Assignee: The University of AkronInventors: Jiang Zhe, Li Du

Publication number: 20160334396Abstract: In various aspects and embodiments, the present invention is directed to versatile, label-free method for the quantitative and qualitative detection of biomarkers and/or other compounds in a fluid sample using functionalized microparticle aggregates. In these methods, micron-scale particles are functionalized to specifically interact with the biomarker being measured and added to the sample to form aggregates, the size and number of which are counted to find a volume fraction and/or number fraction of aggregates in the sample. There is a direct correlation between the volume fraction and number fraction of these aggregates and the concentration of the corresponding biomarker. By comparing the measured volume fraction and/or number fraction of aggregates in the sample to a calibration curve, the concentration of that biomarker may be determined even for biomarkers or other target compounds in samples at very low concentrations, without the need for fluorescence and enzyme labelling of antibodies.Type: ApplicationFiled: September 16, 2015Publication date: November 17, 2016Applicant: The University of AkronInventors: Gang CHENG, Jiang Zhe, Yu Han, HaiYan Wu
