With a solid electrolyte, high energy density and thin packaging, solid-state batteries are getting smaller and enabling devices to be implanted in more parts of the body.

It has been more than six decades since Åke Senning implanted the first heart pacemaker in a patient. Even though today’s pacemakers have improved treatment considerably, the same principles apply: power is supplied from a battery to a pulse generator to maintain an adequate heart rate in the patient.

A similar principle can be applied to medical practices such as neuromodulation, which alters nerve activity through targeted electrical stimulus. Neuromodulation was originally developed to treat chronic pain through deep brain stimulation, but as the subject has become more widely understood, its use has spread from pain reli…
