SCENARIOS

WHERE TO INSTALL IT 

The fluttering artificial leave could be potentially installed in buildings (facades, balconies, roofs...), bridges, highways, roads, tunnels, bicycle paths, vehicles surfaces (cars, buses, truck, metro, train, planes, ships…), structures (to provide ventilation and/ or shadow), etc.

FUNCTIONS/ AREAS 

Lighting (Public outdoor spaces, public and private housing), audio, sound, screens, information displays), pavilions, parasols, walls, battery, personal devices (mobiles, computers...), remote sensor networks (monitoring devices ...), etc. 

DEVICE

DEVICE CONCEPT 

The artificial leaf includes a pair of sheets attached by a holder. Both sheets consist on a flexible sandwich-structured composite blade. The outer skins are made by attaching two mylar metalized sheets. The core materials are piezoelectric stalk and OLED light. 

The fluttering leaf works on a simple principle. The sheets are set into motion by wind airflow, which bends the blade back and forth. The piezoelectric stalk vibrates converting mechanical energy into electrical current powering the OLED Light embedded in the large leaf. The mylar metalized sheets act as a mirror amplifying the OLED light. 

CONFIGURATION 

In order to serve different purposes the electrical energy produced by the leaf can be stored in a capacitor to power different type of electronic devices depending on the context and needs. 

The unit can be parallelized giving the ability to the system to scale from small to large surfaces and therefore providing the system with the potential to blend naturally into urban and natural environments serving to different purposes. 

The system outcome can be enhanced by combining it with other harvesting technologies such as solar cells.

CONCEPT

PARASIT PARADIGM

Fluttering artificial leave is a cost effective and scalable power generator device harvesting energy from wind. The proposal aims to investigate the potential and feasibility of harvesting energy from the wind in constrained locations. Citizens and small organizations can “parasite” urban and natural spaces to collect wind energy from anywhere opening the possibility to continuously scavenge otherwise wasted energy from the environment. They can convert wind energy into electrical power in order to fulfill different practical and emotional needs.

INTERACTION POTENTIAL 

The device converge science and art enabling users to interact with natural processes and translate then into pragmatical and emotional experiences. 

The system would also have the potential to express visually the complex interaction between wind and the environment we live in. Intricate patterns of light and shadow, similar to the way light filters through the leaves of trees, could be intentionally projected onto the walls and floor as sunlight passes through this kinetic membrane to serve to different purposes.
