Linear plasmas, compared to small-area low-temperature plasma jets, offer a larger single-treatment area with brush-like pattern, making them highly promising for various applications. This paper introduces the design of an adjustable linear source that operates under atmospheric pressure at 2.45 GHz. The integrated microwave theory dielectric barrier discharge principles, utilizing resonant structure based on microstrip power divider one end open and other shorted. ground plane was replaced...
Fundamental insights into the function of neural circuits often follows from advances in methodologies and tools for neuroscience. Electrode- optical- based stimulation methods have been used widely neuro-modulation with high resolution. However, they are suffering inherent invasive surgical procedure. Ultrasound has proved as a promising technology neuro-stimulation non-invasive manner. no portable ultrasound system developed particularly neuro-stimulation. The utilities currently assembled...
Objective.Ultrasound neuromodulation has become an emerging method for the therapy of neurodegenerative and psychiatric diseases. The phased array ultrasonic transducer enables multi-target ultrasound in small animals, but relatively large size mass thick cables limit free movement animals. Furthermore, spatial interference may occur during brain stimulation with multiple micro transducers.Approach.In this study, we developed a miniature power used virtual source time inversion 3D printing...
