The new device — the result of a collaboration between pediatricians and engineers — is a small wireless set of electrodes worn on the mother’s breast that measures the amount of milk expressed during a feeding.

An impossible composer to pin down, Machover has written a traditional grand opera such as “Resurrection,” based on Tolstoy’s novel, and “Brain Opera,” which is just that, using electrodes on your noggin.

All lithium-ion batteries work roughly the same way: Cells are clustered inside the battery casing, and lithium ions move between the electrodes in each cell, generating an electric current.

The researchers inserted a bundle of fine micro wires, capable of recording the action potential of a single neuron, through the hollow inner canal of depth electrodes implanted as part of the epilepsy procedure.

The problem is that such technology works by forming bubbles of oxygen on the surface of electrodes deep within the molten regolith itself.
