The development of a flexible electronic skin (e-skin) highly sensitive to multimodal vibrations and a specialized sensing ability is of great interest for a plethora of applications, such as tactile sensors for robots, seismology, healthcare, and wearable electronics. Here, we present an e-skin design characterized by a bioinspired, microhexagonal structure coated with single-walled carbon nanotubes (SWCNTs) using an ultrasonic spray method. We have demonstrated the outstanding performances of

This paper presents a study on incorporation of carbon nanotubes (CNTs) in fiber-reinforced plastics for real-time structural health monitoring. CNTs dispersed in a solvent were uniformly spray-coated on the surfaces of glass fiber fabrics, which were then layed-up and impregnated with an unsaturated polyester resin using vacuum-assisted resin transfer molding to form composite samples. Prior to resin infusion, electrodes were embedded on the periphery as well as between the plies for electrical

In this study, we investigated the gauge factor and compressive modulus of hybrid nanocomposites of exfoliated graphite nanoplatelets (xGnP) and multiwalled carbon nanotubes (MWCNTs) in a polydimethylsiloxane matrix under compressive strain. Mechanical and electrical tests were conducted to investigate the effects of nanofiller wt %, the xGnP size, and xGnP:MWCNT ratio on the compressive modulus and sensitivity of the sensors. It was found that nanofiller wt %, the xGnP size, and xGnP:MWCNT rati

Abstract The rapid depletion and adverse environmental impacts of fossil fuels necessitate the development of alternative sources of sustainable and ecofriendly energy to address the increasing energy demand due to population growth and technological advancement. Energy harvesting is a major strategy for the generation of sustainable and clean energy. It involves the scavenging and subsequent conversion of the energy from the surroundings into usable electrical energy. In this study, the convers
