Most of us know pectin as a key ingredient for making delicious jellies and jams, not as a component for a complex hybrid device that links biological and electronic systems. But a team of Italian scientists have built on previous work using pectin with a high degree of methylation as the medium to create a new architecture of hybrid device with a double-layered polyelectrolyte that alone drives memristive behavior. A memristive device is a synapse analogue, a device that has a memory. Its behavior in a certain moment depends on its previous activity, similar to the way information in the human brain is transmitted from one neuron to another.
“In this research, we applied materials generally used in the pharmaceutical and food industries in our electrochemical devices,” said Angelica Cifa...
