The Technology:
The technology allows leadless, electrode-free bioelectronic stimulation powered solely by light. It offers safe, precise, and flexible activation of cardiac and neural tissue with ultra-low optical energy, eliminating wires, metals, and genetic manipulation. The result is a minimally invasive platform with strong potential for next-generation medical devices and therapeutic interfaces.
The system is built on thin, flexible p-type silicon membranes engineered through a rapid stain-etching process that forms a nanoporous / non-porous heterojunction. Under visible or NIR illumination, the junction generates strong photoelectrochemical currents sufficient to depolarize excitable tissues.
The structure requires no dopant modulations or metal electrodes—the charge separation emerges from the porosity-induced band alignment. The membrane conforms naturally to soft tissues, ensuring stable contact and reliable optical activation in both cardiac and neural settings.
Key Advantages:
• Leadless and electrode-free: No wires, metals, or implanted leads.
• Low-energy stimulation: Effective at mW/mm² optical power levels.
• Biocompatible single-material design: Pure silicon, no composite interfaces.
• Flexible and conformal: Adapts to moving tissues (heart, nerves, muscle).
• NIR capability: Allows deeper tissue penetration and minimally invasive delivery.
• Simple fabrication: Scalable, low-cost process using standard materials.
Applications:
• Cardiac pacing: Leadless, optically driven pacing and multi-site resynchronization.
• Neuro-modulation: Peripheral nerve stimulation for pain, motor recovery, or rehabilitation.
• Bioelectronic medicine: Soft interfaces for modulation of organs and nerve pathways.
• Implantable devices: Foundation for battery-free or wire-free stimulators.
• Research tools: Precise activation of cardiac and neural circuits in preclinical studies.
