Integrating Traditional Chinese Medicine with Triboelectric Nanogenerators for Self-Powered Electro-acupuncture

Objective: The integration of traditional Chinese medicine (TCM) practices with modern technologies continues to yield innovative breakthroughs across diverse domains. This study explored a novel amalgamation of acupuncture, a well-established TCM technique, with triboelectric nanogenerators (TENG), a cutting-edge energy harvesting technology. The focus is on transforming the coiled head of acupuncture needles into a multifunctional sensor capable of harnessing mechanical energy provided by the practitioner through the triboelectric effect.

Methods: Our approach involved the design and fabrication of a TENG sensor on the coiled head of acupuncture needle. The sensor comprised a triboelectric layer of polydimethylsiloxane (PDMS) infused with multi-walled carbon nanotubes (MWCNTs), an insulating layer, and a conductive layer. This integration allowed the conversion of mechanical energy generated from acupuncture stimulation into electrical energy, facilitating self-powered electroacupuncture.

Results: The sensor is distinguished by its high compressibility, durability, and sensitivity to mechanical stimuli. Through rigorous experimentation, we showed that mechanical stimulation activated the TENG sensor, generating electrical power and enabling the development of self-powered electroacupuncture systems. This dual functionality not only augmented the therapeutic effects of electroacupuncture but also provided a self-sustaining energy source for the treatment process.

Conclusion: This research represents a convergence of ancient TCM wisdom with state-of-the-art innovations in energy harvesting, paving the way for interdisciplinary collaborations between traditional medicine practices and modern technologies.
