Novel Biological Sources for Implantable Battery Materials

Where will the next source of electrode materials for batteries to power edible medical devices come from? Would you believe, from marine cuttlefish? Researchers at Carnegie Mellon University, Pittsburgh, PA, say that melanin pigments in cuttlefish ink provides the perfect chemistry and nanostructure to power tiny electronic devices that can be either ingested or implanted into the body for applications ranging from biosensing to drug delivery.

Transistor for High-Performance Devices at Low Voltage

A team of scientists at Penn State, University Park, PA, say that a new type of transistor could make fast, low-power computing devices possible for energy-constrained applications such as implantable medical electronics, smart sensor networks, and ultra-mobile computing. Called a near broken-gap tunnel field effect transistor (TFET), the new device uses the quantum mechanical tunneling of electrons through an ultrathin energy barrier to provide high current at low voltage.

Automating and Accelerating Telemetry Device Testing

The value of highly accurate, automated, and measurable testing for medical devices cannot be overestimated. As devices become more complex, and patient care becomes increasingly personalized, it’s never been more essential to ensure that each medical device performs reliably and exactly to specifications. Realistically, the first, tenth, and hundredth device off the production line must perform identically, regardless of the test station operator or other test environment variables.
