MDT’s ultra‑low‑power TMR1370 magnetic switch promises multi‑year standby for CGM wearables, cutting battery‑replacement costs
Executive summary: MDT launched the TMR1370 magnetic switch IC with a maximum supply current of 50 nA, enabling over two years of standby operation in continuous glucose monitoring (CGM) devices. The ultra‑low power draw significantly extends battery life of CGM wearables, reducing the frequency of battery replacements and lowering total cost of ownership for patients and healthcare providers.
Who is involved: MultiDimension Technology Co., Ltd. (MDT), CGM device manufacturers, and end‑users of CGM systems.
Likely next: MDT will engage with CGM makers for design‑in evaluations, aiming for volume production and shipments in the fourth quarter of 2026.
MultiDimension Technology Co., Ltd. (MDT) announced the TMR1370, a tunnelling magnetoresistive switch that draws a maximum of 50 nA and enables continuous glucose monitoring devices to stay in standby for more than two years on a single battery charge. The component expands MDT’s existing CGM sensor portfolio and addresses a key pain point for patients and providers: frequent battery replacements. By delivering ultra‑low power consumption, the IC could improve the total cost of ownership of CGM systems and strengthen MDT’s position in the medical‑sensor market.

Analysis — what this means
Likely next events
- MDT to provide TMR1370 samples to leading CGM manufacturers in Q3 2026 for qualification.
- First volume production of TMR1370 expected in Q4 2026, targeting major CGM platforms.
Sectors affected
- Continuous glucose monitoring (CGM) wearables
- Medical device sensor components
Regulatory implications
- Component must comply with ISO 13485 medical‑device quality standards; MDT will supply relevant documentation to customers.
- The IC may need to meet IEC 60601‑1 safety requirements for electrical medical equipment.
Historical parallels
- MDT’s TMR1228D always‑on magnetic switch (July 2026) delivered microamp‑level power consumption for smart‑metering applications.
- Earlier 2025 release of MDT’s TMR1150 low‑power switch achieved 18‑month standby in industrial sensors.
