Title: Innovations by Inventor Li Du
Introduction
Li Du is an accomplished inventor based in Akron, OH, known for his significant contributions to the field of sensor technology. With a total of four patents to his name, Du has developed innovative solutions that enhance the measurement and detection of forces and wear particles in various applications.
Latest Patents
One of Du's latest inventions is a wearable inductive-force sensor. This device provides high-sensitivity dynamic measurements of both normal and shear forces. It utilizes three spiral planar force sensing coils, allowing for the measurement of shear force in the x and y directions, as well as normal force in the z direction. The sensor is designed to be mounted in various locations, such as the insole of a shoe, enabling real-time force sensing of the forces applied to a patient's feet during movement. The accompanying force-measurement electronics employ resonance-frequency division signal multiplexing to monitor the response of the force sensing coils, ensuring minimal complexity while maintaining high sensitivity.
Another notable patent is the integrated ultrasonic-inductive pulse sensor for wear debris detection. This apparatus is designed to detect wear particles in a fluid and includes an inlet and outlet channel. An ultrasonic transducer generates an acoustic wave that defines an acoustic focal zone located between these channels. The flow path is shaped to restrict the fluid flow within the acoustic focal zone. The inductive pulse sensor features multiple flow channels and planar coils wound around them, allowing for the detection of wear particles based on changes in the electrical properties of the coils. A single combined excitation signal is sent to all planar coils simultaneously, and the detection system measures a single output for the multiple flow channels.
