Research

Different signals,one body.

Built on the real-time noise-rejection algorithm first patented in 1997, IKI runs five parallel research domains. Each one carries its own patent, and all of them sit on the same biomarker layer.

01
KANSEI
Affect
Affect

Quantify the emotions people can’t consciously register — and the responses they can’t put into words — continuously, from brain waves and pulse.

Sensors
EEG + PPG
Target
Sensibility / affect
Status
Patent pending / World Top-50 Inventions
Applied areas
  • Mental healthcare
  • Engagement / attention evaluation in learning content
  • Subject evaluation in product UX
  • Reaction measurement for content and creative
02
SLEEP
Five-stage sleep staging
Sleep Stages

Five-stage sleep staging — wake, REM, light, moderate, deep — from a single pulse signal, no electrodes.

Sensors
PPG (pulse only)
Target
Five-stage sleep classification
Status
Patent granted
Applied areas
  • At-home sleep monitoring
  • Sleep evaluation in clinical trials
  • Front-end screening for sleep apnea
  • Fatigue management in occupational health
03
FACE
Heart rate & blood pressure
Camera Sensing (rPPG)

Camera-only sensing. Read heart rate, HRV and blood-pressure trends from a face on screen.

Sensors
RGB camera
Target
Heart rate / HRV / blood-pressure trend
Status
Patent granted
Applied areas
  • Telehealth triage
  • In-vehicle driver monitoring
  • Pre-measurement in waiting rooms and check-ups
  • Remote wellness in office and education
04
VOICE
Silent speech
Silent Speech

Read words from the mouth, even when there is no voice to hear.

Sensors
Camera video (subtle mouth movement)
Target
Words and phrases
Status
Patent granted
Applied areas
  • Communication support for people with speech impairment
  • Silent input in noisy environments
  • Voice-free input in confidential settings
  • Cross-lingual accessibility
05
HORMONE
Hormone levels
Hormone Dynamics

Track hormone dynamics from biosignals — without a needle, without a lab.

Sensors
Existing biosignal features
Target
Circulating hormone dynamics
Status
Patent pending
Applied areas
  • Menstrual cycle tracking
  • Chronic stress (cortisol) monitoring
  • Research into early detection of endocrine disorders
  • Surrogate read-outs for hormone dynamics in drug-discovery PoCs
