The topic is as interesting as the title. After decades of effort, Scientists have devised a way to generate electricity from brain. Researchers from Massachusetts Institute of Technology (MIT) have designed an implantable fuel cell that can generate electricity from a fluid around the brain (cerebrospinal fluid). The result of the experiment was a success since it produced a few hundred microwatts of power from glucose within the cerebrospinal fluid. No adverse physiological effects have been reported so far. This small amount of generated power is of course not enough to run a small fan or any small appliance. But the inventors are not thinking of utilizing this energy to power the appliances. Instead, scientists have planned to make use of this energy in bio-medical field. The amount of electricity produced is enough to power the latest, futuristic and highly efficient brain implants that can help the paralyzed patients to move their limbs.
According to the team leader and computer scientist Rahul Sarpeshkar, the new fuel cells can be a great remedy for paralysis or blindness. Currently, most brain implants are powered through inductive power transfer. The power is transferred either wirelessly or by single use batteries. The major disadvantage of such single use batteries is that they have to be replaced surgically after several years. In comparison, the new fuel cell is made up of platinum (a metal that has good track record of being safe in human body). Moreover, according to Rahul Sarpeshkar the new fuel cell can work for decades with no need of replacement. These new cells will first be tested on humans and animals.
