1. What the Invention Is
The invention is a Self-Sustaining Biometric Access Architecture that eliminates the need for chemical batteries in smart locks. It integrates high-efficiency solar and piezoelectric energy harvesting into a unified power management system. This system captures energy from ambient light and mechanical user touch, storing it in a solid-state supercapacitor array to power a high-precision capacitive fingerprint sensor and a low-energy solenoid actuator.

2. The Problem It Solves
Traditional smart locks suffer from "Battery Anxiety" and high maintenance overhead. Lithium and alkaline batteries fail in extreme temperatures (?20°C to +60°C), leak over time, and require replacement every 6–12 months. In industrial or remote settings (telecom towers, logistics, agriculture), a dead battery means a total security lockout or expensive manual intervention. Furthermore, standard Flash memory is prone to data corruption during power fluctuations, leading to loss of critical biometric credentials.

3. Benefit Over Existing Technologies
Zero Maintenance: A true "fit-and-forget" solution with a 10+ year operational lifespan and no recurring battery costs.

Indestructible Data: Utilizing FRAM (Ferroelectric RAM), it ensures 100-year biometric data retention and 200x lower power consumption compared to existing smart locks.

Extreme Durability: Unlike batteries, supercapacitors are weather-resilient and support 500,000+ charge cycles without degradation.

Eco-Friendly: Eliminates toxic electronic waste, making it the only viable "Green Security" option for ESG-compliant corporations.
