These Low-Power Sensors Are Compatible With Wearable Gadget Applications
Rahul Kalvapalle — May 11, 2026 — Tech
Murata, a world-renowned leader in the design and manufacturing of electronic components, has proceeded with the introduction of the MRMS166R and MRMS168R low power sensors, which are able to operate on exceptionally low current levels that make them ideal for applications such as health care and Internet of Things environments where the compactness of power sources can act as a mitigating factor for battery life.
What distinguishes the sensors is their ability to handle magnetic switching without mechanical components. This is possible by the ability to detect the presence of a magnetic field and generate signals that allow devices to shift between active and sleep modes, helping reduce standby energy use.
The components are built for integration into small devices such as medical patches, capsule endoscopes and wearable electronics.

Trend Themes
-
Ultra-low-power Magnetic Sensors — Continuous magnetic-field detection at microampere currents allows always-on monitoring in compact wearables, supporting devices with multi-year battery lifespans.
-
Mechanical-free Magnetic Switching — Solid-state magnetic switching replaces mechanical reed switches, creating slimmer and more reliable form factors for implantable and patchable medical devices.
-
Sensor-driven Sleep Mode Management — Advanced sensor-triggered active/sleep transitions dramatically reduce standby consumption, shifting design constraints from battery capacity toward smarter power orchestration.
Industry Implications
-
Wearable Health Tech — Miniaturized, low-current sensors enable non-invasive continuous vitals tracking through patches and garments that minimize battery maintenance.
-
Capsule Endoscopy and Implantables — Battery-constrained ingestible and implantable devices can leverage magnetic-triggered state changes to extend operational periods inside the body.
-
Iot Asset Tracking and Smart Tags — Always-on magnetic detection permits long-lived asset trackers and smart tags that remain passive until environmental changes require reporting.
