A Biomimetic Artificial Neuron Matrix System Based on Carbon Nanotubes for Tactile Sensing of e-Skin

Abstract

In this study, a carbon nanotube (CNT) flexible strain sensor was fabricated with CNT based epoxy and rubber composites for tactile sensing. The flexible strain sensor can be fabricated as a long fibrous sensor and it also may be able to measure large deformation and contact information on a structure. The long and flexible sensor can be considered to be a continuous sensor like a dendrite of a neuron in the human body and we named the sensor as a biomimetic artificial neuron. For the application of the neuron in biomimetic engineering, an ANMS (Artificial Neuron Matrix System) was developed by means of the array of the neurons with a signal processing system. Moreover, a strain positioning algorithm was also developed to find localized tactile information of the ANMS with Labview for the application of an artificial e-skin.

Biomimetic Strategies for Sensing Biological Species

“…They used this sensor for studying the direct electron transfer of hemoglobin—which can be extended to other redox-active enzymes—and fabricating a sensitive voltammetric biosensor for H 2 O 2 . Combining the above two strategies ( i.e ., nanotubes and composites), Kim et al [ 52 ] employed carbon nanotube (CNT)-based epoxy and rubber composites by fabricating a CNT flexible strain sensor for tactile sensing. Such a sensor uses a long fibrous sensor and can measure large deformation and contact information on a structure.…”
