microelectrodes
Miniature neural probes
Microelectrodes are extremely small electrodes used to measure or stimulate electrical activity at the cellular level.
They're essential tools in neuroscience for recording signals from individual neurons: The researchers inserted microelectrodes into the brain tissue to map neural activity.
They also appear in electrochemistry and biomedical devices where precision at microscopic scales matters.
