A recent EDN article highlights research being done by the Interuniversity Microelectronics Center (IMEC) into the design of interfaces between living cells and nanoelectronic devices. One project involves developing an artificial synapse that directly links to living neurons. The difficult part is developing an IC with a surface that neurons can live on. Current devices keep neurons alive for only a few weeks. The researchers are also having success at guiding the growth of a neuron so that its synapses align with special transducers that can translate electrical activity. The article talks about several other interesting technologies under development at IMEC. For more details, see the IMEC Bioelectronics website.
