Development of Wearable Pulsed Magnetic Field Generation Device

Brain waves of different frequencies are generated when the human brain functions, and γ waves are closely associated with higher cognitive functions, such as learning and memory. It has been observed that an electromagnetic field with specific frequency, amplitude, and duty cycle can enhance γ wave oscillation, thereby effectively improving human cognitive function. Building upon this discovery, this paper introduces a wearable pulsed magnetic field generator designed to enhance human cognitive abilities. The device allows for adjustable magnetic induction intensity of the output pulse magnetic field within the range of 0–5 mT, adjustable frequency of the output magnetic field within the range of 0–50 Hz, and adjustable duty cycle of the output magnetic field within the range of 1–50%. Furthermore, the device can generate a 5 Hz pulse wave modulated at 40 Hz (and can also produce a 5 Hz modulation of a 40 Hz pulse wave). The output of the device is both adjustable and stable, making it suitable for conducting experimental studies on cognitive function improvement.
