Bioresorbable devices for sensing, drug delivery, and other purposes have the potential to enhance treatments and provide monitoring. From a materials standpoint, even something as simple as replacing a convention electrical wire can be challenging. Recently, a research team in Korea have published a paper describing their work with composite materials for this application. They worked with a mixture of beeswax, tungsten powder, and glycofurol to make a material they call “W-paste”. The resulting material had:

  • high conductivity
  • high mechanical stability
  • can be screen printed
  • has isotropic electrical paths
  • is biocompatible
  • degrades in PBS after about 80 days.
