Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In challenging underwater environments, mechanical actuators must overcome various obstacles and ensure precise and stable control when interacting with fragile and flexible targets. To address these issues, a novel pressure and slip state monitoring sensor (PS-TENG) based on the triboelectric nanogenerator principle was proposed to establish a haptic sensing system for underwater actuators. This sensor can detect pressure at the actuator during gripping and the relative slipping speed between the actuator and the target, allowing for precise control based on feedback signals from the perception system. In this study, we established a theoretical model between pressure and electrical signal, explored material preparation methods and manufacturing steps, conducted performance optimization experiments after producing the prototype, and proposed a signal processing method for the sensor output. Results demonstrated that the sensor can generate an open-circuit voltage signal of up to 45 V at a maximum operating pressure of 13 N. Moreover, within the operating pressure range, the sensor exhibited high sensitivity, reaching up to 4.5 V/N. By analyzing and processing the sensor signals, the actuator can obtain both pressure and relative slipping speed information simultaneously, essential for addressing complex underwater grasping tasks. Our research indicates that the PS-TENG sensor can serve as a reliable and efficient solution for establishing haptic sensing systems in underwater applications. With its excellent performance, this sensor holds broad potential for use in underwater robotics and electronic devices, enabling more versatile and reliable equipment in the future.
