SOMA

A biosensing digital twin for wearable-sensor development. Place virtual sensors on a full-body anatomical model, vary physiological conditions and review the synthetic signals, so design decisions are made before any hardware is built.

  • Whole-body twin: six body systems, 3D tissue sections at 12 skin sites
  • ECG · PPG · EEG · EMG · respiration · capacitance synthesis, with CSV export
  • Sleep apnea: respiration from an epigastric patch, posture and turning conditions
  • Ring blood-pressure monitor: PPG (red/infrared) signals and blood-pressure experiments by hand height

Screen demo

Key screens

10 key screens from the live demo walk through the features. Use the previous and next buttons, the arrow keys or the strip below; open the live demo to try it yourself.

  1. SOMA screen — Simulator home

    01 / 10

    Simulator home

    The starting screen for the three labs: whole-body digital twin, sleep apnea and hand sensing.

    • What each simulator covers and which signals it produces
    • Korean and English; performance modes (auto, low, balanced, high)
  2. SOMA screen — Whole-body digital twin

    02 / 10

    Whole-body digital twin

    Explore synthetic signals on an anatomical-atlas body while changing its structures and physiology.

    • Circulatory, visceral, nervous, skeletal and muscular systems, each with its own opacity
    • Live heart rate, respiration rate, SpO₂ and pulse-wave velocity
    • Rotate, zoom, front view and focus mode
  3. SOMA screen — Heart and lungs view

    03 / 10

    Heart and lungs view

    Switch between whole-body, heart-and-lungs and brain views to focus on a region.

    • Adjustable arterial expansion
    • Toggle muscles and pulsation
  4. SOMA screen — Chest sensor · ECG

    04 / 10

    Chest sensor · ECG

    Choose a site and the sensor is placed on the model, with the synthetic signal for that site.

    • Six sites: wrist, finger, earlobe, forehead, chest, upper arm
    • Six signals: ECG, PPG, EEG, EMG, RESP, CAP
    • Adjustable time window
  5. SOMA screen — Wrist sensor · PPG

    05 / 10

    Wrist sensor · PPG

    Compare PPG waveforms across optical wavelengths and contact conditions.

    • Green 530 nm · Red 660 nm · Infrared 940 nm
    • Adjustable sensor contact
  6. SOMA screen — Motion and physiology

    06 / 10

    Motion and physiology

    Apply motions such as walking or running and see their effect on the signals.

    • Nine motions, including rest, walk, run, sit-to-stand and hand grip
    • Physiology controls and reset to initial conditions
    • Export signal data as CSV
  7. SOMA screen — Sleep apnea · epigastric patch

    07 / 10

    Sleep apnea · epigastric patch

    Respiration is estimated from a single-channel capacitance (CAP) patch on the epigastrium, with ECG and acceleration.

    • Synchronised signals: CAP · ECG · accelerometer XYZ · ECG-derived respiration (EDR)
    • Breathing scenarios: normal, obstruction, loss of drive
    • Fused respiratory rate, periodicity quality, motion-artifact labels
  8. SOMA screen — Posture and patch placement

    08 / 10

    Posture and patch placement

    Switch continuously between supine, left, right and turning in bed, and move the patch to see the signals change.

    • ECG potential and CAP coupling change with patch position
    • Physiology and electrode model: lung compliance, airway resistance, subcutaneous fat and more
    • External gateway input when run locally: up to 32 channels, audio, video and radar features
  9. SOMA screen — Hand sensing · ring BP monitor

    09 / 10

    Hand sensing · ring BP monitor

    An optical ring on the index finger of a full-body patient, exploring PPG and local blood pressure by posture and hand height. The centre view zooms in on the ring and the hand anatomy: skin, muscle, vessels and tendons.

    • Standing, sitting, walking and supine
    • Red/IR PPG, 3-axis acceleration, SpO₂ reference value
    • Circulation view, exaggerated arterial motion
    • Ring contact toggle, turning artifact, CSV export
  10. SOMA screen — Hand height and blood pressure

    10 / 10

    Hand height and blood pressure

    Move the hand above or below the heart and the local arterial pressure waveform follows a hydrostatic model.

    • Heart-level SBP/DBP and hand-height inputs
    • Optical-signal artifacts flagged by movement speed
