Genetic Algorithm optimization for a surgical ultrasonic transducer

An ultrasonic piezoelectric transducer to cut the human tissue or to remove the spinal disc is envisioned to improve efficiency and facilitate the surgeons work. Three genetic algorithms have been developed. The first one is based on conditional genetic operators, the second one is based on a specific crossover operator definition with a local search method, and the third is a combination of both the previous algorithms. The third algorithm is used to optimize the piezoelectric transducer. In less than 5000 simulations the optimizations give an amplitude of the cutting tip of about 4.8 microns.
