Next-generation biocompatible power cells for implantable and wearable medical devices — engineered for life.
Overview
Implantable medical devices — pacemakers, cochlear implants, neural stimulators — are only as reliable as the batteries powering them. Today's lithium-based cells require invasive replacement surgeries every 7–10 years and carry thermal safety risks inside the human body.
God's i Medical Batteries research programme is engineering a new class of biocompatible, wirelessly rechargeable power cells that dramatically extend device lifespans, eliminate replacement surgery risk, and remain absolutely safe within biological tissue environments.
Technology
Solid-state electrolytes using non-toxic lithium phosphate compounds — fully stable in biological saline, with no heavy metal risk to surrounding tissue.
Inductive power transfer through skin — patients hold a charging pad over the implant site for daily top-ups, eliminating all surgery for energy replenishment.
Targeting 15+ year operational life through deep-discharge protection, low self-discharge chemistry, and intelligent charge cycle management firmware.
Thermal management design ensures cell temperature never exceeds 40°C, preventing heat injury to surrounding tissue under all charging and discharge conditions.
Scalable cell architecture from micro-scale (cochlear implants) to mid-scale (pacemakers, neurostimulators) — single platform, multiple device profiles.
Development aligned with ISO 13485 quality systems and IEC 60601-1 safety for active implantable medical devices, targeting CDSCO and FDA pathways.
Applications
Primary application — replacing Li-I₂ cells with wireless-rechargeable solid-state cells to eliminate battery replacement surgeries.
Deep brain stimulators for Parkinson's and epilepsy treatment — high-drain, long-life requirements perfectly matched to our chemistry.
Micro-scale cell variant for inner-ear implants, providing stable power over decades without the need for external battery swaps.
Wearable variant for continuous glucose monitoring and drug delivery systems where longevity and safe form factor are critical.
