The present paper presents a finite element model and analysis for the interaction between a piezoresistive tactile sensor and biological tissues. The tactile sensor is proposed for use in minimally invasive surgery to deliver tactile information of biological tissues to surgeons. The proposed sensor measures the relative hardness of soft contact objects as well as the contact force. Silicone r...

The electron beam radiation method is emitted by electronic accelerators, which can change the chemical physical properties of radiation. Silicone rubber samples after different irradiation intesities were carried out for 1000h aging test, and scanning microscopy (SEM), mechanical tensile hydrophhy angle silicone sample measured, test results shows that: visual apperence did not changed, SEM sh...

To ensure safe coil embolization for cerebral aneurysms, it is important to investigate the contact force between a and an aneurysm wall. Therefore, in our previous study, we developed experimental system measuring biomodel. However, because model was made of silicone rubber, its physical properties, such as friction coefficient, differed from those aneurysms vivo. this using poly (vinyl alcoho...

a dissolved methane sensor based on silicone tube was designed, constructed and optimized.the silicone tube diameter, silicone tube length and helium flow rate (as the carrier gas(were considered as process parameters to be optimized.a continuous stream of helium (50 ml/min) was directed through the tubing, sweeping out the dissolved methane which diffused through the walls of the tubing from t...

STATEMENT OF PROBLEM The success of most non-implant-retained extraoral prostheses depends on retention derived from skin adhesives. Part 1 of this study found that Skin-Prep Protective Dressing improved the retentive properties of adhesives and that Secure(2) Medical Adhesive was stronger than Epithane-3. Part 2 investigates the application of a second layer of adhesive to the prosthesis, whic...
