A 128 × 128 CMOS biosensor array for extracellular recording of neural activity.

A 128 × 128 CMOS biosensor array for extracellular recording of neural activity.

Sensor arrays are a key tool in the field of neuroscience for noninvasive recording of the activity of biological networks, such as dissociated neurons or neural tissue. A high-density sensor array complementary metal-oxide-semiconductor chip is presented with 16 K pixels, a frame rate of 2 kilofram...
