In the high-pressure whirl of modern society, insomnia has become a silent struggle for countless individuals—an urgent issue demanding a solution. The Huishen research team, keenly aware of this challenge, dedicated itself to pioneering the development of dual-mode sleep technology combining microcurrent stimulation and sound therapy. At the time, domestic research in this field was virtually nonexistent, meaning everything had to be built from the ground up.

Sound stimulation required precise calibration of acoustic properties to facilitate a deep "dialogue" with the human endocrine system. Researchers sifted through vast audio samples to identify key parameters that could trigger melatonin secretion from the pineal gland and regulate pituitary hormones—an ongoing process of analyzing complex experimental data. Microcurrent stimulation proved even more challenging, with no prior domestic experience to draw from. Focusing on vagus nerve stimulation, the team painstakingly constructed theoretical models and fine-tuned current intensity and frequency through repeated experimentation, where even the slightest deviation could undo months of effort. Yet, they pressed forward with unwavering determination.

Bringing together experts in acoustics, neurology, biology, and beyond, the team conducted countless optimizations and adjustments. Finally, they achieved seamless synergy between microcurrent and sound stimulation—successfully bridging a critical technological gap in the field and offering restful sleep to those who had long struggled with insomnia.
