Purple-Pulse
Dual-Motor Vibrator with Focused Electrostimulation & Pressure-Wave Technology
The Purple-Pulse combines a cam-driven thrusting mechanism (≤120 strokes/min, 20 mm stroke) with dual-zone electrostimulation targeting the anterior vaginal wall and clitoral complex. Electrodes are carbon-loaded medical-grade silicone — flexible, biocompatible, and ISO 10993-5 cytotoxicity-certified. A piezoelectric transducer delivers focused pneumatic pressure pulses (0.3–2.5 bar, 5–20 Hz), creating a suction-like sensation through rapid air displacement rather than direct tissue contact. The 1,800 mAh cell yields ~60 min combined runtime. All electrical outputs hardware-limited to 12 mA with thermal cutoff at 42 °C.
Key Features
Engineered for performance, comfort, and safety.
81 Mode Matrix (9×9)
Independent control of 9 thrusting speeds (cam-driven linear actuator, 10–120 strokes/min) and 9 vibration patterns (BLDC motor, 1,200–12,000 RPM). Each combination activates different sensory pathways — mechanoreceptors for thrust, vibrotactile receptors for vibration.
Dual-Zone E-Stim (7 Levels)
Seven intensity steps (0.3–12 mA) with independent G-spot and clitoral electrode zones. Biphasic square-wave pulses at 20–200 Hz. Carbon-filled conductive silicone electrodes (ISO 10993-5 certified) flex with the body for consistent contact without rigid metal edges.
Pneumatic Pressure-Wave Module
Piezoelectric ceramic transducer generates focused air-displacement pulses (0.3–2.5 bar, 5–20 Hz) within a sealed chamber over the clitoral area. Unlike direct-contact vibration, this creates rhythmic positive/negative pressure cycles — similar to the mechanism in clinical clitoral suction devices studied in JSMT (2021).
20 mm Linear Actuator + Dampener
Precision cam mechanism with 20 mm stroke length and integrated 20 mm spring dampener. The dampener absorbs inertial forces at stroke reversal, keeping electrode contact stable during thrusting — critical for uninterrupted e-stim delivery at frequencies above 50 Hz.
Bluetooth 5.0 Waveform Editor
App-controlled e-stim pattern designer: adjustable pulse width (50–500 µs), frequency (2–200 Hz), amplitude (0–100%), and ramp times (0.1–5.0 s). Save unlimited presets. Share encrypted patterns with partners. Optional "auto-escalate" mode gradually increases intensity over configurable 5–30 min windows.
Platinum-Cured Medical Silicone
Body is platinum-catalysed silicone (Shore A 20) — non-porous, autoclavable (though not required), and inherently hypoallergenic. No plasticisers, phthalates, or BPA. Conductive electrode zones use carbon-particle-loaded silicone for seamless flex-electrode integration.
Ergonomic 30° G-Spot Curve
Anatomically designed based on MRI-derived vaginal canal geometry (Foldes & Buisson, 2009). The 30° anterior curve directs the thrusting tip toward the urethral sponge / anterior fornix — the tissue region most densely innervated by the pudendal nerve's dorsal branch.
IPX7 with E-Stim Auto-Cutoff
Fully sealed with silicone compression gaskets. Conductivity sensor triggers automatic e-stim shutdown on full immersion. Vibration and thrusting remain operational underwater. E-stim re-enables when surface-dry contact is detected.
Electrical Stimulation Modes
Biphasic square-wave pulses across 7 intensity levels (0.3–12 mA) and 5 patterns, plus 3 piezoelectric pressure-wave intensities. Overlaid on 81 vibration/thrust combinations for 8,505 theoretical permutations.

The Science Behind E-Stim
Pudendal Nerve Targeting
The electrode placement targets the pudendal nerve (S2-S4 sacral roots) which innervates the perineum, labia, clitoris, and lower vagina. Electrical stimulation of pudendal afferents activates the nucleus of Onuf in the sacral spinal cord, enhancing pelvic floor reflexes.
Piezoelectric Shockwave Therapy
Focused radial pressure waves (0.5–3.0 bar) trigger mechanotransduction in endothelial cells. This activates eNOS (endothelial nitric oxide synthase), releasing NO which relaxes smooth muscle in blood vessel walls, increasing local blood flow by up to 300% — similar to clinical Li-ESWT protocols.
Mechanosensitive Ion Channels
Pressure waves activate Piezo1/2 channels in neuronal and epithelial cell membranes. These mechanosensitive cation channels convert physical force into electrical signals, creating an amplified sensory cascade independent of the direct electrical stimulation pathway.
Neurochemical Response
Combined vibration + e-stim + shockwave creates a multi-pathway neurochemical response: serotonin (5-HT) from raphe nuclei, oxytocin from the paraventricular nucleus, dopamine from the ventral tegmental area, and β-endorphin from the arcuate nucleus — a synergistic cascade not achievable by any single modality.
