Blade-leaf technology
[Category : - DESIGN PATENTS]
[Viewed 10 times]
Abstract
A synthetic blade-leaf apparatus comprising a multi-layer flexible structure capable of harvesting solar and mechanical energy simultaneously. The device integrates photovoltaic micro-film, piezoelectric bending elements, thermal-regulating surfaces, and conductive micro-channels, all embedded within a grass-like polymer blade. When arranged in large clusters, the system forms an energy-generating synthetic turf capable of continuous outdoor operation.

Technical Field
The invention relates to renewable energy systems and, more particularly, to flexible synthetic energy-harvesting blades modeled after natural plant leaves.
---
Background
Conventional photovoltaic panels require rigid structures, fixed mounting angles, and discrete installation areas. Natural grass, however, offers massive surface area across open spaces while remaining flexible, wind-responsive, and durable. There exists a need for a solar-active synthetic blade that combines the surface area advantage and flexibility of grass with the energy capture ability of photovoltaic and piezoelectric materials.

Summary of the Invention
The invention provides a multi-functional synthetic blade-leaf capable of collecting solar energy, converting mechanical motion to electrical energy, reducing surface heat, and routing power through an integrated subsurface grid. Each blade operates independently yet connects to a shared ground grid controller (GGC).

Detailed Description
1. Blade Structure
Each synthetic blade comprises:
1. Light-Absorbing Polymer Shell
UV-resistant polymer with micro-textured grooves to increase photon capture.
2. Photovoltaic Micro-Film (PV-1 Layer)
Flexible thin-film semiconductor laminated onto the inner surface of the blade.
Converts incident sunlight into direct electrical current.
3. Piezoelectric Motion Layer (PZ-2 Layer)
Positioned beneath the PV film.
Generates electrical charge when the blade bends under wind or foot traffic.
4. Thermal Dissipation Coating
Reduces heat accumulation and protects PV layers from thermal decay.
5. Embedded Conductive Micro-Channels
Micro-wires or printed conductive pathways that transport generated energy downward.
---
2. Base Connector Node (“Root Terminal”)
Located at the bottom of each blade, this component performs:
Electrical consolidation of solar and piezoelectric output
Voltage stabilization
Mechanical anchoring
Moisture sealing
The node couples to a subsurface Ground Grid Controller.
---
3. Ground Grid Controller (GGC)
The GGC is a distributed power-management matrix that:
Collects energy from hundreds to thousands of blades
Performs voltage equalization
Stores excess energy in battery modules or exports it to external systems
Provides system-wide diagnostics and automatic shutdown protocols

Claims (Sample Draft)
1. A synthetic energy-harvesting blade comprising:
a flexible polymer shell, a photovoltaic micro-film layer, a piezoelectric motion layer, and conductive micro-channels, wherein the layers operate concurrently to generate electrical output.
2. The synthetic blade of Claim 1, wherein the blade mimics natural leaf curvature to optimize light incidence and mechanical flex response.
3. The system comprising a plurality of blades, each connected to a base connector node and a ground grid controller configured to aggregate electrical output.
4. The synthetic turf network, wherein the distributed blades provide continuous energy generation via both solar absorption and motion-induced piezoelectric excitation.
