LEESOL Core Technology 1

CS-tACS: Proprietary Brainwave Entrainment Technology Designed by LEESOL

Built on Leesol’s patented CS-tACS technology,
our neurofeedback-driven brainwave entrainment
solution modulates the nervous system through precise electrical stimulation, opening new
possibilities for the prevention and treatment
of sleep disorders, depression, stress-related
conditions, and neurodegenerative diseases
such as Alzheimer’s.

LEESOL Core Technology 2

Deep-Brainwave Sync Tech : DBST™

LEESOL's DBST™ continuously monitors each patient's brainwave activity during entrainment therapy, leveraging neurofeedback to dynamically optimize treatment in real time — delivering a truly personalized therapeutic experience tailored to every individual's unique condition.

Current Limitations

Achieving true brainwave entrainment demands stimulation powerful enough to overcome the body's natural epidermal barriers. Yet conventional approaches fall short — unable to penetrate deeply enough to reach the brain, leaving the full potential of entrainment therapy unrealized.

DBST™ Technology

Powered by a proprietary electrical stimulation technology, DBST™ achieves what conventional methods cannot — penetrating deep into the brain to maximize cerebral absorption and unlock true deep-brain brainwave entrainment.



DBST™ targets and activates the brain regions governing higher-order cognitive functions — including working memory, sustained attention, information integration, and sensory perception — to measurably enhance focus and accelerate cognitive processing speed. processing speed.

Resoflow™

(Resonance + Flow)

Neofield™ (Neo + Field): A potential therapy
device applying "new electric field" technology
that effectively improves blood circulation
and restores biological rhythms through the
micro-vibration of cells.

LEESOL Core Technology 4

Neoclear™

By seamlessly integrating DBST™ and
Chirp-Resonance Sync (CRS™) technologies,
this advanced solution brings the brain's
biological rhythms into perfect synchronization —
restoring optimal neural activity and returning
the mind to its ideal functional state.
