Questions

Why is the ear a better location for biometric sensors than the wrist?

The skin around the ear canal and temple is thin, rich in micro-vasculature, and directly influenced by the brain's regulatory centres. PPG signals captured here are far less susceptible to motion artefacts than wrist-based readings, and the proximity to the head means autonomic changes — like HRV shifts during stress — are reflected more quickly and accurately.

What does Sychedelic detect that a standard fitness tracker cannot?

Standard fitness trackers report steps, calories, and basic heart rate. Sychedelic tracks cognitive state in real time using PPG-derived HRV metrics — RMSSD, LF/HF ratio, and pNN50 — sampled at 100 Hz near the ear. It classifies your autonomic state across five zones and uses that classification to gate when tDCS stimulation begins, making it a proactive cognitive system rather than a passive data logger.

Is cognitive wearable technology safe for everyday use?

Sychedelic uses two non-invasive modalities: optical PPG sensing and tDCS at 2 mA, both of which have extensive safety records in research literature. Bikson et al. (2016) reviewed 33,200 tDCS sessions with no serious adverse events at standard parameters. As with any wearable, absolute contraindications (active epilepsy, implanted cardiac devices) apply.
