Background:

• Logic gates are fundamental to digital electronics, forming the basis of combinational and sequential circuits.
• Triboelectric nanogenerators (TENGs) convert mechanical energy to electrical energy, offering potential as mechanical-stimuli-responsive input devices.
• Metal-organic frameworks (MOFs) like MIL-53 possess unique properties such as high surface area and tunable porosity, making them suitable for advanced material applications.

Purpose of the Study:

• To develop a novel logic gate implementation using a TENG device.
• To investigate the performance of a MIL-53 impregnated TENG (MS-TENG) as a binary input for logic operations.
• To demonstrate the potential industrial applications of MOF-based TENGs in control systems.

Main Methods:

• Fabrication of a TENG device using a MIL-53 impregnated sponge.
• Analysis of the MS-TENG in contact-separation mode to characterize its electrical output.
• Simulation of logic gates and a half-adder using LabVIEW software with the MS-TENG as the input source.

Main Results:

• The MS-TENG device demonstrated optimal performance with 4 wt.% MIL-53 particle filling.
• The fabricated MS-TENG achieved a maximum output voltage of 44.2 V, current of 0.9 µA, and transferred charge of 6 nC.
• Successful simulation of logic gates, a half-adder, and power plant control operations using the MS-TENG as a mechanical trigger.

Conclusions:

• The MIL-53 impregnated TENG serves as an effective binary input device for logic gate operations.
• This research highlights the potential of MOF-based TENGs for practical applications in digital electronics and industrial automation.
• The study validates the use of TENGs for simulating complex control systems, including those found in power plants.
