Summary of SOLID STATE BATTERY IS SMALL ENOUGH FOR MEDICAL IMPLANTS
Ilika has launched the Stereax® M50, a millimetre-scale solid-state battery designed for medical implants like smart contact lenses. This technology enables miniaturization, biocompatibility, and customizable form factors, addressing critical needs in MedTech such as long life-span, wireless data transfer, and injection-friendly designs for applications including neurostimulation and heart rhythm monitoring without requiring frequent surgical replacements.
Parts used in the Stereax M50 Project:
- Stereax M50 millimetre scale solid state batteries
- Smart contact lenses
- Implantable medical devices
- Wireless data transfer systems
- Neurostimulation attachment components
- Heart rhythm monitoring modules
UK battery maker Ilika has officially launched its millimetre scale solid state battery for medical implants, including smart contact lenses.
Ilika a few days ago announced the launch of Stereax® M50 mm-scale solid-state batteries designed for medical implants. The Stereax M50 brings all the benefits of the Stereax products whilst taking solid-state batteries to a new level of miniaturisation. Bringing form factor choice enabling medical device innovations that have previously been limited by the available battery technology.
The implantable medical device industry has a growing need for miniaturized, long-life power sources to enable wireless data transfer from increasingly sophisticated devices that are improving patients’ lives
said Mike Nagy, Chief Technology Officer, Endotronix.
The MedTech space is one of the most challenging environments for battery technologies. Batteries need to be small enough to be unobtrusive, enabling implantable devices to be charged in a way that does not restrict a patient. The batteries need to have as long a life-span as possible, avoiding the risks of repeated surgical intervention. They also need to be biocompatible so that they do not pose a risk of leakage. Each device application may require different sizes and form factors, which can now be accommodated with the customisable battery sizes and shapes enabled by the Stereax M50. Innovation in applications that require injection into the blood stream, monitoring heart rhythm or attachment onto the peripheral nervous system for neurostimulation can be enabled with this technology. These batteries enable self-sustaining power sources that do not need to be changed regularly or use inconvenient cabling.
