The Proof Of Concept

Research of existing technologies



  • Materials: Solar Cells
  • Technologies: Advanced Energy Harvesting

Carbon charges your smart phone and it will be coming with Solar cells that use the solar energy to charge up. The design of this carbon smart watch is similar to any analog watch that is in the market and will be using the high tech solar cells that uses indoor and outdoor solar energy that can charge the smart phone.

Carbon has an energy output of 1 Amp and 5 Volts that can be used to power many devices, like a range of smart phones, cameras, smart watches etc that can be charges by using USB. The approximate USB input charge time is 30 minutes and Solar Charge time is approximate- ly 8 hours in full sun light. The LED Battery shows colors indicating the battery levels.

Carbon Smartwatch uses an advanced energy harvesting technology including a DC to DC boost converter and maximum power point track- ing. Both influence charge time along with battery over/under charging thresholds preventing battery damage.

  • Materials: Organic / Norganic Materials

A thermoelectric generator is a device that can convert heat, or a tem- perature difference, into electric energy. Using the small but significant temperature difference between skin and air, Professor Cho and his team have been able to produce this tiny and wearable thermoelectric generator.

KAIST’s generator is extremely light and flexible and produces electricity from the heat of the human body. Professor Cho confirmed that the gen- erator could also charge smartphones.

To date, two types of TE generators have been developed. These are based either on organic or inorganic materials, the former being car- bon-based compounds found in biological systems and the latter mole- cules lacking carbon found in geological systems.




  • Designer: Max Donelan
  • Manufacturer/Lab: Simon Fraser University
  • Technology: Biomechanical Energy Harvesting

A team of researchers at Simon Fraser University has invented a device that could tap into one of the most reliable sources of clean, cheap en- ergy: you.

Called the Biomechanical Energy Harvester, it fits around each knee and, using the force naturally created at the end of each step, generates elec- tricity as you walk.

Max Donelan, one of the device’s inventors, said at normal walking speed, and with little extra physical effort, the device can generate about five watts of constant electricity — meaning a single minute of walking could power a cellphone for 10 minutes or an MP3 player for 40.

The device can also operate in continuous generation mode, which creates more power, but also puts extra resistance on the joint and requires more effort on the part of the wearer.
