PVC gel smart sensor for robotics sensing applications: an experimental and finite element simulation study ^*

Abstract

Research is now being done on soft electroactive polymers (EAPs), such as polyvinyl chloride (PVC) gel, as an example, for use in soft robotics and smart sensors. Although the sensing behavior of PVC gel has not yet been thoroughly investigated, it has been determined that this material reacts in some way to the stimuli that come from the outside. PVC gels are being utilized to construct a broad variety of different kinds of smart sensors due to the fact that their deformation may be endlessly configured by variations in electrode arrangement, applied mechanical stress, and the amount of plasticizer contained within the gel. In this study, experimental characterizations and the results of finite element simulations are discussed for a PVC gel compression sensor. A simulation of what happens to PVC gel when it is compressed from the outside using mechanical force has been built using the COMSOL Multiphysics, which is a finite element simulation software. This simulation was used to create the simulation. In addition, experimental measurements of PVC gels are carried out in order to validate the underlying principles that have been presented thus far by providing context for the results of the simulations and to validate the findings of the simulations effectively. Based on the findings, it appears that the suggested sensor is able to detect compression at a variety of amplitudes and speeds.

Enhancing Photovoltaic Panel Efficiency With an Iot-Enabled Robotic Cleaning System – A Comprehensive Review

“…Based on the literature review of IoT-based robotic cleaners for PV panel cleaning, the expected results can include: 1. Improved cleaning efficiency: The use of IoT-based robotic cleaners can result in improved cleaning efficiency of PV panels compared to traditional manual cleaning methods [1,5,6,10,13,17,19]. This can lead to increased energy output of the panels, ultimately resulting in decreased operating costs.…”

“…One such industry is the field of photovoltaic (PV) panel cleaning, where IoT-based robotic cleaners can help improve the efficiency of cleaning and monitoring the panels [4,5]. The use of PV panels has been on the rise in recent years, as they provide a sustainable and cost-effective source of energy [6]. However, the efficiency of these panels can be reduced due to the accumulation of dust, dirt, and other debris on their surface [7].…”

“…The sensing properties of these materials were recently investigated and found to be adsorptive-like in nature [ 8 , 9 , 10 ]. The fundamental studies investigating the underlying mechanisms of mechanoelectrical transduction include compressive loading applications.…”

Innovative SCADA-Based Oil Refinery Control with Arduino Integration Using Labview

“…At the heart of the system, the master station and its sub-masters collate data from various RTUs and often furnish an operator interface for data visualization and remote control of the distributed sites. In larger telemetry systems, sub-master sites undertake the role of gathering information from remote sites and function as relays back to the central control master station, enhancing the scalability of the SCADA system [6,9]. SCADA technology has a rich history, with its origins tracing back to the early 1960s.…”
