Modeling Electrical Resistance Behavior of Soft and Flexible Piezoresistive Sensors Based on Carbon-Black/Silicone Elastomer Composites

Abstract Soft and flexible strain piezoresistive sensors are gaining interest in wearable robotic applications, but resistance relaxation limits the widespread use of sensors. As soft, flexible, stretchable sensors, they can easily be retrofitted into any existing hand. To understand three different elastomers were used to fabricate soft The experimental results showed that sensor has good linearity scalability while their is strongly influenced by stretching speed modulus elastomer. Thus, Kevin Voigt model was adopted describe sensor’s change during process. sufficient carbon black/elastomer filler when stretched before fracturing conductive filler. However, fractures, invalid. behavior indicates elongation must not exceed causes fracture.
