Effect of electrical stimulation generated by self-powered systems for tissue repair

Area of Science:

• Biomedical Engineering
• Regenerative Medicine
• Bioelectricity

Background:

• Bioelectricity is crucial for tissue repair processes.
• Nanogenerators harvest biomechanical energy to produce electrical stimulation (ES).
• ES has applications in sensing, tissue repair, and cardiac pacing.

Purpose of the Study:

• To review the role of ES from self-powered nanogenerators in tissue repair.
• To elucidate cellular responses and effects on endogenous electric fields during ES-enhanced regeneration.
• To summarize mechanisms of ES in promoting repair across different tissues.

Main Methods:

• Review of literature on nanogenerators and electrical stimulation in tissue repair.
• Analysis of cellular responses to ES in various tissue types.
• Discussion of ES parameters and nanogenerator-tissue matching.

Main Results:

• ES from nanogenerators shows potential in repairing bone, tendon, nerve, skin, and myocardial tissues.
• Differential cellular responses and effects on endogenous electric fields were observed.
• Mechanisms by which ES promotes repair in specific tissues were summarized.

Conclusions:

• Self-powered nanogenerators offer a promising approach for tissue repair by simulating endogenous bioelectrical signals.
• Matching ES parameters to specific tissue needs is critical for therapeutic success.
• Further research into challenges and perspectives is needed to advance nanogenerator-based tissue therapy.
