luminpet / light


We have known that people who live in poverty afar find it hard to achieve a convenient and safe lighting resource due to no electricity locally. We hope that a low-cost solution can be offered to those people trapped. Only one glass of water will allow Luminpet to provide a stable lighting for a period of time.
We used a thin film that can change its shape under various moisture to make a roller structure. When the roller is under two environments of eitherbeing dry or being moist, it will run losing the balance due to the different deformation of the lateral thin films to generate a small LED light.
