Haptic information is crucial in the execution of precise dexterous manipulations. Laparoscopic surgery, a type minimally invasive requires that surgeon senses force about tissue through forceps, because he or she cannot touch organs directly. We propose concept surgical grasping forceps with enhanced sensorimotor capability based on attaching vibrator to forceps' grip by evoking stochastic resonance (SR) effect. To apply appropriate vibrations, summing network FitzHugh-Nagumo neurons was...
In this study, we experimentally demonstrate a class of lightweight acoustic metamaterial barriers that block low-frequency sound. The barrier is composed thin rubber membrane coated over stiff honeycomb plate. Our findings, combined with high-fidelity finite element simulations, the sound insulation performance surpasses mass law in three distinct frequency ranges: (a) stiffness dominates up to 140 Hz, (b) degeneracy and destructive superposition high-order natural modes dominate within...
This paper reports experimental results on a surgical grasping forceps with vibration actuator that enhances tactile perception ability. A short-time exposure of receptors to sub-sensory white-noise is known improve phenomenon, called stochastic resonance (SR) in the somatosensory system, expected enhance sense touch when weak applied fingertip, and thereby associated motor skills. lead zirconate titanate (PZT) was attached grip forceps. passive sensory test has been conducted for healthy...
This paper reports experimental results on a surgical grasping forceps that equips vibration actuator to enhance tactile perception ability. A short-time exposure of receptors sub-sensory white-noise is known improve phenomenon, called stochastic resonance (SR) in the somatosensory system, expected sense touch when weak applied, and thereby associated motor skills. To investigate effect noise intensity, summing network FitzHugh-Nagumo model neurons was built. The simulation showed...
In this research, theoretical transmission losses (TL) of finite flat plate with simple support, clamped, and free boundary condition are derived considering eigenmodes the by modal expansions. Theoretical TLs demonstrated to agree well those obtained numerical approach. Compared TL mass law, decrease at eigen frequencies panel exhibits almost constant value certain frequency range below coincidence frequency. This band ranges from where radiation efficiency exceeds 1
