Porous-Structure-Promoted Tribo-Induced High-Performance Self-Powered Tactile Sensor toward Remote Human-Machine...

Area of Science:

• Materials Science
• Nanotechnology
• Robotics

Background:

• Intelligent human-machine interaction (HMI) systems require advanced self-powered tactile sensors.
• Existing sensors often lack versatile functions or sufficient sensitivity.

Purpose of the Study:

• To develop a hybrid self-powered porous-structured tactile sensor (SPTS) with dual optical and electrical sensing capabilities.
• To enhance the performance of triboelectric nanogenerators and triboelectrification-induced electroluminescence through a porous structure.

Main Methods:

• Monolithic integration of a porous triboelectrification-induced electroluminescence (TIEL) component and a single-electrode triboelectric nanogenerator.
• Optimization of porous structure and sensor parameters for enhanced charge generation and TIEL intensity.
• Development of a programmable dual-mode HMI system for practical demonstrations.

Main Results:

• The SPTS demonstrated significantly improved TIEL intensity (three times at 10 kPa) and enhanced triboelectricity.
• Achieved high sensing performance in both optical and electrical modes.
• Successfully demonstrated remote control of an intelligent vehicle and a computer game via finger touch trajectories.

Conclusions:

• The proposed SPTS offers an economical and effective method for high-performance self-powered tactile sensing.
• The dual-mode functionality facilitates advanced HMI applications.
• Broad potential applications in intelligent robots, augmented reality, wearable electronics, and smart home systems.
