A combinatorial biofilm treatment involving a low dose of antibiotics along with small amount electricity is known as the bioelectric effect (BE). When an external electric field or current applied, biofilms can be affected by resulting electrostatic force. Our group researching maximization force through integration both alternating and direct currents, voltage below electrolysis threshold (0.82 V). To validate efficacy this technology, in present work we investigated two major...
Abstract Background Nebulizers are medical devices that deliver aerosolized medication directly to lungs treat a variety of respiratory diseases. However, breathing patterns, respiration rates, airway diameters, and amounts drugs delivered by nebulizers may be disease dependent. Method In this study, we developed simulator consisting an model, artificial lung, flow sensor, aerosol collecting filter. Various patterns were generated using linear actuator air cylinder. We tested six home (jet...
The functional components of vibrating mesh nebulizers are a piezoelectric ceramic with mounted on one side, reservoir, and driving circuit. material vibrates at specific intrinsic frequency, when the mechanical resonance frequency applied electrical signal match, vibration amplitude is greatest. In present study, nebulizing performances were tested respect to voltage after automatic tuning (ARFT) and/or impedance matching (IM) for salbutamol glycerol solutions. A 1% mismatch reduced output...
Effective oral care is a critical requirement to maintain high quality of life. Most diseases are caused by plaque (oral biofilm), which also correlated with systemic diseases. A common method remove biofilm brushing teeth toothpaste. However, 3.5 billion people in the world have diseases, meaning that more efficient methods removing biofilms needed. We developed toothbrush applying bioelectric effect (BE) utilizing an electric force for removal. It demonstrated significantly higher removal...

Effective oral care is important for maintaining a high quality of life. Therefore, plaque control can prevent the development and recurrence periodontitis. Brushing with toothbrush toothpaste common way to remove plaque; however, excessive brushing or abrasive cause wear tear on dental crown. Hence, we aimed quantitatively compare plaque-removal efficiency tooth toothbrushes using bioelectric effect (BE) those electric–mechanical toothbrushes. To generate BE signal, an electronic circuit...
Bioelectric effect is known as combinatorial biofilm treatment with low dose of antibiotics small electricity. When external electric field or current are applied, biofilms can be affected by the electrostatic force, non-uniform distribution essential electrolytes, induction activity enzyme, and increase permeability biofilms. In this work, we have focused on reduction applied power consumption that could avoid water electrolysis which was one major challenges for biomedical applications. We...
