Many hearing implants won't help people with inner ear damage or auditory nerve problems, but the brainstem implants that do frequently do an incomplete job. Soon, however, there might be a far better solution. Researchers have designed a conformable electrode implant that should more effectively counter inner ear damage. It uses body-safe, resilient platinum for electrodes, but overcomes the metal's usual stiffness thanks to micron-level machining inspired by kirigami paper cutting. Once wrapped in silicone, it's highly conductive but can cling tightly to the auditory brainstem and send more targeted signals than in conventional implants.
