What are the drawbacks of gsr sensor?
Best insight from top research papers
The drawbacks of GSR sensors include nonlinearity, hysteresis, and temperature-dependent output, which can reduce measurement accuracy . Additionally, the uptake of GSR sensors in clinical practice may be hindered by factors such as skin reactions to sensors, the need for frequent calibrations and device insertions, especially challenging for young children and adolescents . On the other hand, the response time of graphene-based sensors to gas molecules, such as CO, NH3, SO2, and CO2, is typically slow due to a significant potential barrier hindering direct adsorption at defective sites on the graphene sheet . These factors collectively highlight areas for improvement in GSR sensor technology to enhance accuracy, usability, and response times.
