Novel Micro Sensors and Estimation Algorithms for Physiological Measurements
This talk will describe the development of micro sensors and estimation algorithms for a number of interesting medical applications. Ultra small sensors are developed and evaluated for the estimation of muscle forces in neuromuscular diseases. Novel sensors are developed for in-vivo measurement of normal and shear elastic properties in tissues. Battery-less wireless force sensors that utilize piezoelectric energy generation are developed for knee replacement implants. Inductive coupling with a nonlinear adaptive observer is used to enable a battery-less wireless acoustic sensor. In each medical application, the talk will describe the novelty of the sensing technique, development of estimation algorithms, sensor fabrication and experimental results.
