Conductive silicone rubber has great advantages for tactile sensing applications. The electrical behavior of the elastomeric material is rate-dependent and exhibit hysteresis upon cyclic loading. Several constitutive models were developed for mechanical simulation of this material upon loading and unloading. One of the successful approaches to model the time-dependent behavior of elastomers is ...

Recently, we have reported use of Optical Coherence Tomography (OCT) and vibrational analysis to determine the resonant frequency of a material from which the moduli of decellularized dermis, pig skin, silicone rubber and chemically modified dermis were calculated. In this paper, we present data on viscoelastic mechanical properties of extracellular matrices and silicone rubber at frequencies a...

background substrates in medical science are hydrophilic polymers undergoing volume expansion when exposed to culture medium that influenced on cell attachment. although crosslinking by chemical agents could reduce water uptake and promote mechanical properties, these networks would release crosslinking agents. in order to overcome this weakness, silicone rubber is used and reinforced by nanocl...

A kind of new material suitable for flexible tactile sensor and its preparation method will be introduced. The tactile sensor applied this new material and method can be used in many kinds of occasions which contacting pressure measurement such as humanoid robot sensitive skin, medicine and so on. This material is composite of carbon black and silicone rubber filled nano-SiO2 as the main raw ma...

In recent years, many tactile sensors have been developed with the advancement in robotics. For example, there are sensors that measure the distribution of the contact state or the force distribution. Among the several tactile sensors in use currently, none can evaluate the sense of gentle touch. We have developed a fibratus tactile sensor that uses the property of reflection. Using this sensor...

Application of combining herbal medicine and biomedical material science to nerve regeneration is a new approach. In this study, we describe a novel use of purified genipin, which can be extracted from Gardenia jasminoides Ellis, fixing the gelatin to be an extracellular matrix for peripheral nerve regeneration. A 10-mm gap of rat sciatic nerve was created between the proximal and distal nerve ...

Vulnerability evaluation of various biometric systems should be conducted and its results should be available to potential users.

Minimally invasive surgery (MIS) has become a preferred method for surgeons for the last two decades, thanks to its crucial advantages over classical open surgeries. Although MIS has some advantages, it has a few drawbacks. Since MIS technology includes performing surgery through small incisions using long slender tools, one of the main drawbacks of MIS becomes the loss of direct contact with t...
