Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cosmetic and medical devices for skin regeneration lack precision in bioelectric signaling, failing to effectively control the release and expression of specific regenerative proteins, which are crucial for targeted skin treatment and regeneration.
Innovation Solution
A bioelectric stimulator that delivers precise electrical signals to control protein expression in skin tissue, combining with a composition of stem cells, growth factors, and nutrients to stimulate skin regeneration, using a combination of adipose-derived stem cells, microRNAs, exosomes, and hydrogels, and utilizing specific electrical signals to induce the release of proteins like SDF-1, IGF-1, VEGF, and tropoelastin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional electrical stimulation is applied to skin tissue, then general stimulation effect is achieved, but precise control of specific protein expression is lost
Solution Approach 1:
The electrical stimulation signal is segmented into multiple frequency components, where each frequency specifically triggers the expression of a different regenerative protein (e.g., 1 Hz for VEGF, 10 Hz for IGF-1, 100 Hz for FGF). This segmentation allows precise control of protein expression without requiring complex device architecture.
Solution Approach 2:
The system changes the frequency parameter of the electrical signal to control different biological outcomes. By varying frequency while keeping other parameters constant, the system achieves specific protein expression control through a simple device mechanism.
2Measurement precision
If electrical stimulation is applied to recruit stem cells, then stem cell homing is enhanced, but control over specific stem cell differentiation is reduced
Solution Approach 1:
The stimulation protocol is segmented into distinct frequency phases: lower frequencies (1-10 Hz) recruit stem cells to the treatment area, while higher frequencies (50-100 Hz) direct differentiation toward specific lineages. This temporal and frequency-based segmentation enables precise control of the entire stem cell journey from recruitment to differentiation.
Solution Approach 2:
The system employs periodic electrical stimulation with specific frequency patterns to guide stem cell behavior. Periodic application of different frequencies at different time points creates a controlled differentiation sequence without requiring complex real-time adjustments.

AI summary
A skin regeneration therapy combining precise bioelectric signals, light, and biologics for skin treatment and regeneration. Precise bioelectric signals give clear instructions to the stimulated cell DNA/RNA to produce specific regenerative proteins on demand. Bioelectric signals give clear instructions to cell membranes on what to let in and what to let out and serve as an equivalent or surrogate of environmental stimuli to cause a cell action in response.
