A novel approach to touch voltage risk assessment for gas pipelines in shared transmission corridors
IET Science, Measurement & Technology, 2023 Touch voltages are more likely to appear on long‐distance pipelines that lie in shared corridors with transmission lines. The touch voltage level varies with soil resistivity and can become hazardous while maintenance is being undertaken, necessitating ...

A Force–Voltage Responsivity Stabilization Method for Piezoelectric Touch Panels in the Internet of Things [PDF]
2020 IEEE International Conference on Flexible and Printable Sensors and Systems (FLEPS), 2020 Piezoelectric force touch panels are extensively utilized as human-machine interfaces for 3-dimensional touch sensing in internet of things (IoT) applications. However, the unstable force voltage responsivity issue induced by different touch orientations limits the successful use of piezoelectric touch panels.
