Efforts made at Clarkson University have demonstrated implantable biofuel cells that can be used to one day generate power for medical implants in humans.

In their most recent feature article, Katz and coworkers have showcased their work towards an implantable energy generation device that could one day be made compatible in humans. One of the largest problems in making implantable biofuel cells practical is generating enough voltage and current to power a device. Using electrodes comprised of compressed multi-walled carbon nanotubes, the researchers have been able to generate 470 mV open circuit voltage, at a current of 5 mA short circuit. Coupled with a DC-DC converter, it was enough power to operate a pacemaker from a single device.

The article goes into detailed explanation, refreshingly, about the current constraints and considerations to be made in order to advance this technology further. One such aspect is to improve the amount of active enzymes on the electrode surface, which is currently only measured at 6% electrically active on the electrodes. By improving this single factor, it is believed that the current density could be large enough for a small (0.5 cm² electrodes) implantable device.

It is postulated in the paper that one day miniature devices could be implanted in the human brain, where a constant source of glucose fuel could be delivered in order to power devices. Who knows, we may soon be pouring over literature from the comfort of our own cranium computers!

Thermoelectric power generation technology aims to harvest and convert waste heat into electricity. Researchers are looking for not toxic, abundant and inexpensive new materials with good thermal and chemical stability in air at high temperatures.

Quaternary oxyselenides (BiCuSeO) have been addressed as a promising thermoelectric system to use in sustainable energy generation from waste heat. Thermoelectric conversion efficiencies for these materials is described by the dimensionless figure of merit, ZT, which has reached a maximum value of about 1.4. Textured Bi_0.875Ba_0.125CuSeO has outperformed this value due to its low thermal conductivity and improved electrical transport properties, which has been achieved by increasing carrier concentration through optimising dopants.

In a recent article by Li-Dong Zhao and co-workers, a hot-forging process was used to produce grains oriented along a preferential axis. A higher carrier mobility along the direction perpendicular to the pressing direction was also obtained. The microstructure was then observed using X-ray diffraction (XRD) and scanning electron microscopy (SEM).

The highest ZT value ever reported for oxygen containing materials was achieved making oxyselenides a valid candidate for medium temperature thermoelectric applications.

Conductive polymer hydrogels (CPHs) are of significant interest for a broad range of applications, including biosensors, lithium batteries, supercapacitors and biofuel cells.

The cutting edge of the field is in creating 3D nanostructured CPHs for electrochemical devices, and a recent review by Lijia Pan, Guihua Yu et al. focuses on new synthetic techniques to make these nanostructured materials, along with a discussion of their potential applications.

One of the greatest strengths of the CPHs is their versatility.  Many different conductive polymers, such as PEDOT, PAni, PPy and PTH can be used as the electrical backbone of the material, and there are many templating techniques (such as inkjet printing, copolymerization and template-directed growth) that can be used to achieve the desired morphology and electrical properties.

An exciting new synthetic route to nanostructured CPHs is gelation of a PAni network using phytic acid as the gelator and dopant.  The interactions between the phytic acid molecules and the PAni chains allows for the formation of “foam-like nanostructures which are constructed with coral-like dendritic nanofibers with uniform diameters of 60–100 nm).”  The PAni chains allow for excellent electrical conductivity and the as-prepared hydrogel is suitable for spray coating and inkjet printing.  PAni hydrogels as high-performance electrodes for glucose sensors and supercapacitors have been demonstrated, and other CPHs show great promise for battery electrodes, in drug delivery devices, and in the removal of free radicals from the environment.
