Innovative technique uses sweat to power bio-battery

Choi and team from Binghamton University have innovated, for the first time, a flexible and stretchable microbial fuel cell monolithically integrated into a single sheet of textile substrate.

Biological fuel cells can use enzymes or microorganism to scavenge the microbiological energy from the wearer’s body fluids such as sweat, saliva, blood and tears. It can act as a potential fuel to support bacterial viability, providing the long-term operation of the microbial fuel cells. In the future, textile based bio batteries can be integrated into wearable electronics.

Bio Battery is a device in which organic or inorganic substrate is converted into electrical energy with the help of biological agents.

Advantages:

  • Energy density is 10 times greater than lithium batteries.
  • Utilises renewable catalyst and are inexpensive.
  • Allows for instant recharge .
  • These batteries are a source of non flammable and non-toxic fuel.
  • A great alternative renewable power source

Disadvantages

Not able to retain the energy for a long time.

Bio battery applications:

1) Portable charging e.g. Cell phones

2) Medical implants: Insulin pumps, pacemakers.

3) Replacing batteries in toys.
