Researchers at Linköping University in Sweden have developed artificial neurons that demonstrate 15 of the 20 characteristics of biological neural cells and can communicate with natural neurons in the body. The researchers call their device the “conductance-based organic electrochemical neuron,” or c-OECN, and it is based on materials that can conduct a negative charge, including organic electrochemical transistors and n-type conducting polymers. By printing thousands of such transistors on a flexible substrate, the researchers have been able to create artificial…

A team of researchers at the Harvard Wyss Institute have developed a soft, hydrogel scaffold that can function as a living electrode for brain-computer interface applications. The researchers used electrically conductive materials and created a porous and flexible scaffold using a freeze-drying process. They then seeded the scaffold with human neural progenitor cells (NPCs) and cultured the scaffolds for extended periods, prompting the cells to differentiate into a variety of neurons and astrocytes. The researchers hope that the resulting 'living…
