Using natural body heat or temperature to light up LEDs

Many students these days are experimenting with peizo-electric theory to generate electricity and lighting things up. Combining this theory with the seeback effect, LED lighting is made possible.

Selecting the right type of material that will generate a charge due to temperature difference is critical in lighting up an LEDs.

The amazing thing about LED is the low voltage and current required to light up. This really enable many different applications and electrical generating methods to be applied.

E.g an awesome student in Canada using body heat to light up a torch light. All these without a need for battery.

This might just replace solar panels or be an additional arsenal towards our go-green campaign. This form or renewal energy is both free (from the body heat point of view) and seemingly perpetual.

Stretchable LED Lighting? | Events and Electronics

If lightings can be stretched, how do you think we can enhance our spaces and minimise / reduce lighting costs?

Putting mechanical engineering considerations aside for now? We probably can explore the following;

1. LED Lightings as visual displays for smart clothing
2. LED Lighting for curve screens in Smart Phones
3. Smart LED Lighting for architectural facade (indoor / outdoor ("although challenging it may be"))
4. LED Lighting displays covering different surface area when necessary for advertising and creative industry.

By bringing mechanical engineering considerations in lighting, we might need to explore the following;
1. Stretchable host material for the LEDs where it is both conductive and insulated from touch.
2. Types of material for the LEDs that is able to light up with movable conductive electrical supply
