A wireless headband that reads forehead skin temperature with two infrared sensors. Nothing touches the skin electrically, and there is no cable to the computer.

| Sensors | Two Melexis MLX90632 infrared thermopiles, medical accuracy grade, in two pods on the forehead |
| Field of view | 50° per sensor |
| Resolution | Tracks temperature changes smaller than 0.1 °C (bench test, 2026) |
| Environment sensing | Humidity and temperature measured inside the sensor enclosure |
| Connection | Bluetooth Low Energy on a pre-certified module (USB on the current prototype) |
| Power | Rechargeable battery; training is disabled while the headset is charging |
| Skin contact | The band only; no electrodes, gels or conductive parts |
| Fit | Adjustable band; rear dial planned for production |

Designed for a clean signal
PFX001 digitizes the temperature at the sensor itself, so there is no separate measurement box between the headset and the computer. It measures the conditions inside its own enclosure, and sends the signal over Bluetooth, so the client isn't tethered to the desk.
The goal is a trace that follows small, slow changes smoothly, which is where pIR HEG training happens.
PFX001 is a prototype in validation. It is not available for sale, and we are not taking orders or deposits.
