Smartphone Measurements
Smartphone sensors provide one layer of Hyperion's multimodal measurement system, alongside active neurological tests, metabolic data, psychophysical context and optional wearables.
PPG uses optical changes in blood volume to support heart-rate and heart-rate-variability measurement through the smartphone camera and flash. Hyperion does not reduce readiness to this signal alone.
The Future of Smartphone Diagnostics
PPG is one component of a broader research direction. Modern smartphones provide sensors that may support additional physiological analysis:
Phonocardiography (PCG)
Heart sound analysis, straight from your microphone.
Voice biomarkers
Fatigue markers hidden in 30 seconds of your speech — already part of your test. Learn more
Pulse Transit Time (PTT)
Blood pressure estimation without a cuff — based on the delay between heart signal and fingertip signal.
Ballistocardiography (BCG)
Measuring micro-movements of the chest caused by each heartbeat.
Micro-tremor analysis
Detecting sympathetic nervous system arousal invisible to the naked eye.
Stabilometry
Balance system fatigue assessment through micro-body movement analysis.
Saccadic Eye Movement
Measuring eye movement delays as an indicator of cognitive fatigue and neural load.
…and more
Hyperion is developing a smartphone-based measurement environment that brings these signals together over time.
