Biofuel cell developed in Finland

09.11.2006
A compact, inexpensive, disposable power source for consumer applications

An enzyme-based power source is a viable source of electricity for the rapidly proliferating RFID tags used in the medical sector and logistics. Applications include plasters containing a memory circuit and measuring electrode for temperature, and sensors monitoring food quality. VTT Technical Research Centre of Finland is developing printable biofuel cells in which enzymes convert the energy bound in the renewable fuels - sugar, alcohols, etc. - into electricity.

VTT is developing an enzyme-based power source that converts the chemical energy bound in the organic compounds (fuels) into electricity. The enzymes act as catalysts that facilitate the use of e.g. sugar and alcohols as fuels. VTT's invention is based on the use of the fungal laccase enzyme on the cathodic compartment. A patent on the solution, which has yielded a 0.7V voltage with a current density of 20 microampere per square metre, is pending. Laccase is also suitable for printable technology applications as it retains its ability to produce electricity even when printed on paper.

Printable enzyme-based power sources are compact, inexpensive and disposable. Potential applications include sensors used in the logistics chain, temperature sensors for food products, adhesive medical sensors and printed screens. Applications will probably become more widespread in the 2010s.

The enzymes replace the traditional precious metal catalysts, and the fuel cells operate with good overall efficiency in standard pressure at ambient temperature. The ability to mass-produce the fuel cells as printable products will enable a dramatic reduction in costs. They are also disposable, thanks to the biodegradable raw materials and fuels.

The development of biofuel cells is being carried out within the framework of the Printable Miniature Power Sources project, in which the Helsinki University of Technology (coordinator), VTT and Åbo Akademi are acting as research partners. The later stages of the project concern the development of a mass production method based on printable technology. VTT is also continuing its research in an EU project concerned with the use of biofuel cells as a power source for biosensors.

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
