The Inner Balance Bluetooth (BTLE) sensor is designed for maximum safety. It operates at an output power of 0.5 milliwatts (mW) or less, which is significantly lower than a typical mobile phone (which ranges from 250 mW to 2000 mW). Additionally, the Bluetooth emitter is located in the module that clips to your clothing—not in the sensor attached to your ear—keeping the source of the signal away from your head.
Improved Title: Safety and EMF Levels of the Inner Balance Bluetooth Sensor
Overview
A common question regarding wireless technology is the level of electromagnetic field (EMF) radiation emitted during use. The Inner Balance Bluetooth sensor utilizes Bluetooth 4.0 (Bluetooth Low Energy or BTLE), a standard specifically designed to minimize power consumption and radio frequency (RF) output.
Comparative Radiation Levels
To put the output of the Inner Balance sensor into perspective, it is helpful to compare it to standard mobile devices:
-
Inner Balance BTLE Sensor: Works at an output power range of 0.5 milliwatts (mW) or less.
-
Standard Mobile Phones: Typically emit between 250 mW and 2000 mW during active use.
Because the sensor operates at such a low power threshold, its EMF radiation is negligible compared to the devices most people carry throughout the day.
Strategic Component Placement
HeartMath has prioritized user safety in the physical design of the hardware:
-
Ear Sensor: The portion of the device that clips to your earlobe contains no Bluetooth emitter. It is a passive component that uses light to measure your pulse.
-
Clothing Module: The tiny Bluetooth transmitter is housed entirely within the module that clips to your shirt or garment. This ensures that the source of the wireless signal is kept at a distance from your head and brain.
Regulatory Compliance
The Inner Balance Bluetooth Sensor is fully compliant with all applicable FCC (Federal Communications Commission) testing and safety standards. These tests ensure that the device operates well within the legal and safety limits for wireless transmission.
Summary
The Inner Balance Bluetooth sensor provides a safe, low-emission way to track your coherence. By using “Low Energy” technology and placing the transmitter away from the head, HeartMath ensures that your focus can remain entirely on your heart-centered practice.
