Abstract
Many sensors require mechanical durability to resist immense or impulsive pressure and large elasticity, so that they can be installed in or assimilated into the outer layer of artificial skin on robots. Given these demanding requirements, we adopted natural rubber (NR-latex) and developed a new method (NM) for curing NR-latex by the application of a magnetic field under electrolytic polymerization. The aim of the present work is to clarify the new manufacturing process for NR-latex embedded with magnetic compound fluid (MCF) as a conductive filler, and the contribution of the optimization of the new process for sensor. We first clarify the effect of the magnetic field on the enhancement of the NR-latex MCF rubber created by the alignment of magnetic clusters of MCF. Next, SEM, XRD, Raman spectroscopy, and XPS are used for morphological and microscopic observation of the electrolytically polymerized MCF rubber, and a chemical approach measuring pH and ORP of the MCF rubber liquid was used to investigate the process of electrolytic polymerization with a physical mode. We elucidate why the MCF rubber produced by the NM is enhanced with high sensitivity and long-term stability. This process of producing MCF rubber by the NM is closely related to the development of a highly sensitive sensor.
Highlights
Sensors are currently used in many fields to detect force, temperature, pressure, etc
These characteristics are not, limited to the sensors in robotics; sensors with mechanical durability are required in other engineering fields
These results suggest that the magnetic compound fluid (MCF) rubber grows at the position between the maximum magnetic field strength and the maximum magnetic field gradient
Summary
Sensors are currently used in many fields to detect force, temperature, pressure, etc. Certain sensors should be suitable for installation as an outer layer on robots, or for assimilation into an artificial skin. These characteristics are not, limited to the sensors in robotics; sensors with mechanical durability are required in other engineering fields. One new natural-contact biosensor has been designed as an interface between humans and machines for nonintrusive and real-time sensing. This sensor utilizes microelectromechanical systems (MEMS) or nanoelectromechanical systems (NEMS) to enable miniature sensors, flexibility remains a fundamental problem
