Researchers in Singapore have come up with a new energy harvesting device which has the capability to generate electricity from the heat produced from our body or any environment where there is a temperature gradient. This new energy harvesting device is named as thermoelectric power generator. This generator produces a power of around 1.3 micro-watts that can be utilized or consumed by implanted medical devices or wireless sensors which are very useful.

This generator consists of a single chip where the total area is just 1X1 cm2 which holds more than 30,000 thermocouples. This device can generate a voltage of around 16.7 volts. They are trying to improve the power output.
