Grounded in real research. Built around your own preferences.
ZAPPIZO's stimulation modes are informed by published research on how rhythmic vibrotactile input affects the brain and body — and refined for you specifically through a preference-learning system, not a one-size-fits-all protocol.
What published research shows about vibrotactile stimulation
Multiple peer-reviewed studies have found that rhythmic vibrotactile stimulation can entrain brain oscillations at the stimulation frequency. Separately, vibrotactile and audio stimulation protocols have been linked to measurable changes in stress, mood, and sleep-related outcomes in published research.
Vibrotactile stimulation and gamma entrainment (2025)
Vibration applied to the hand was shown to entrain 40 Hz gamma brain activity, a frequency band linked to sleep and cognitive benefits in prior research.
Read the studyVibrotactile stimulation entrains somatosensory brain oscillations (2022)
Rhythmic vibrotactile stimulation was found to entrain brain oscillations at the exact stimulation frequency, with effects peaking near 20 Hz.
Read the studyVibroacoustic stimulation and mood, with EEG evidence
A five-week gamma-frequency vibrotactile and auditory stimulation protocol was associated with significant improvement in depression symptoms and measurable EEG changes in responders.
Read the studyVibrotactile-induced sensory-motor rhythms
Vibration alone was shown to induce a specific, named brain rhythm normally associated with movement, without any motor task.
Read the studyVibrotactile stimulation and emotional brain response
Vibrotactile stimulation synced to media content activated the same emotion-related brain regions as normal audiovisual viewing.
Read the studyThese are independent, third-party published studies on vibrotactile stimulation generally. They inform our approach to stimulation design but are not studies of the ZAPPIZO device itself.
Research-informed stimulation, personalized to you
Manual Control
You set the vibration intensity and pattern that feels right for you, in each mode.
Pattern Learning
ZAPPIZO's AI observes your adjustments across sessions to identify what you consistently prefer.
Automatic Personalization
Over time, ZAPPIZO applies your preferred settings automatically — informed by the stimulation patterns supported in the research above, tuned specifically to you.
Early, honest results
We're early. Once we have real user data, we'll present outcomes here as self-reported results with sample size and methodology disclosed — the same transparency approach used by other neurotech wellness brands. Until then, treat anything we say about outcomes as self-reported and early-stage, not clinical-trial-grade evidence.
What ZAPPIZO is — and isn't
ZAPPIZO does not read, sense, or measure brain activity. It does not diagnose or treat any medical condition. ZAPPIZO is a wellness device that lets you control stimulation directly and learns your preferences over time. If you have a diagnosed medical condition, consult a healthcare professional before use.
