About us

Hi, my name is Shmuel Ben-Ezra, for more details...

selected Projects

HIFU for renal denervation

High-intensity focused ultrasound (HIFU) for tissue ablation at large depth (kidney). Action-Physics collaborated with customer from conceptual design, acoustic field modeling and bio-heat transfer calculations, through detailed design and prototype manufacturing, to preclinical and clinical trials.

Twin Piezo motor

Miniature low-frequency motor for stone fragmentation via the onset of acoustic cavitation. The low footprint of the device is adequate for minimally invasive procedures. Action-Physics provided conceptual design, finite-element simulations, detailed design and prototype manufacturing. The project concluded in proof-of-concept experiments and scientific publication.

Ultrasonic comb

Ultrasonic comb for the consumer market, for the eradication of head lice by safe ultrasonic energy. Action-Physics provided the design and build of the first revolutionary working prototype, and participated in proof-of-concept experiments.

What Our partners say

Dr. Harel Primack (R&D manager, AcousticEye Ltd.)

“Shmuel was hired as a consultant to our company on the subject of designing ultrasonic transducers. Since our requirements were quite unique, we needed a creative consultant that will assist us. Shmuel was exactly this person. After thorough study of our needs and understanding the limitations, he came with ideas that later became prototypes. He developed the prototypes and the process of manufacturing them in quantities of tens, and then handed them on to the company for production to my full satisfaction. Shmuel proved to be creative, knowledgeable, trustworthy, diligent and a nice person to work with. I highly recommend hiring him for challenging projects.”
