The SAR test, which quantitatively evaluates the thermal effect of electromagnetic waves absorbed by the human body,
It is an essential verification process to prove the safety of a product and gain user trust.

Electromagnetic waves are generated when using electronic devices (cell phones, computers, microwave ovens, etc.) in everyday life. The unit that indicates the amount of energy (unit: W/kg) absorbed by the human or animal body from these electromagnetic waves is the Specific Absorption Rate (SAR).

When the human body is exposed to low-frequency (low-frequency, 1 Hz to 100 kHz) electromagnetic waves, the induced current stimulates nerves (stimulation). Exposure to high-frequency (high-frequency, 100 kHz to 10 GHz) electromagnetic waves causes a thermal effect that raises body temperature. Cell phone electromagnetic waves, being high-frequency, can cause a rise in body temperature, and this thermal effect is quantitatively expressed as SAR.
