Electricity from Blood Sugar--Forum for Applied Microsystems Technology Awards 2011 FAM Research Prize to Dr. Sven Kerzenmacher

Implants that obtain their energy from blood sugar and oxygen: Dr. Sven Kerzenmacher at the Department of Microsystems Engineering (IMTEK) of the University of Freiburg is researching the development of biological fuel cells with the goal of finding an inexhaustible source of power in the human body. He has been awarded the 2011 FAM Research Prize for his dissertation by the Forum for Applied Microsystems Technology (FAM). The prize is worth 2,500 euros.

Researchers have yet to find an optimal method for supplying implantable medical microsystems with electrical energy. The batteries of a pacemaker, for instance, need to be replaced after roughly eight years -- meaning a strenuous and expensive surgical intervention for the patient. An alternative approach is to use rechargeable batteries. However, the necessity of recharging the batteries greatly reduces the patient’s quality of life. The idea behind Sven Kerzenmacher’s research, on the other hand, is the possibility of using of implantable glucose fuel cells on the basis of noble metal catalysts like platinum. Such catalysts are particularly well suited for use in implant systems due to their long-term stability and the fact that they can be sterilized. In the future, systems equipped with these fuel cells could be supplied with power by way of a continuous electrochemical reaction between glucose and oxygen from the tissue fluid.

Kerzenmacher and his team aim to apply a thin coat of the fuel cells they have developed to the surface of the implant.
