      Nizhny Novgorod Institute of Applied Physics named after A.V. Gaponov-Grechov RAS researchers, together with foreign scientists, developed a unique spherical antenna made from piezo-polymer. The new device is designed for optoacoustic tomography and allows real-time monitoring of blood flow with high precision.

      Unlike traditional piezoceramic-based antennas, the new development is ten times more sensitive to optoacoustic signals. This enabled detailed, non-invasive tracking of blood movement in vessels of various diameters—from large arteries to microscopic capillaries.

      The technology developed by Nizhny Novgorod scientists opens prospects for creating a new generation of medical equipment. Such devices can quickly and painlessly diagnose cardiovascular and neurodegenerative diseases. Additionally, the antenna can be used in nondestructive material testing systems.

      According to project leader and head of the ultrasound and optoacoustic diagnostics laboratory at IFP RAS Pavel Subochev, the idea of dividing the antenna into hundreds of independent elements initially seemed impossible. However, the team succeeded, and now the technology opens new horizons for both medicine and fundamental biology.

      It was previously reported that a robotic laboratory system has been launched at the Nizhny Novgorod Regional Center for the Prevention and Control of AIDS and Infectious Diseases.
