Three signals

What Aora measures.

01

Cognitive Load

A real-time read of how hard your brain is working right now. Built from validated self-report and passive sensing.

02

Neural Recovery

How well your brain is recovering between deep-work sessions. The signal your HRV can't see.

03

Burnout Risk

An early-warning trajectory built from the Copenhagen Burnout Inventory and continuous wearable data.

System Architecture

How it works.

Nine independent layers, synchronized in real time — each purpose-built to capture, process, and deliver cognitive state without compromise.

01 / 09

Sensor Layer

Reads raw biological signals from the body.

  • ECG electrodes
  • PPG sensors (blood flow, SpO₂, HR, HRV)
  • Multispectral LEDs
02 / 09

Analog Front-End

Converts extremely weak biosignals into measurable electrical data.

  • Ultra-low-noise amplifiers
  • Signal conditioning circuits
  • Analog ECG/PPG processing
03 / 09

Filtering & Signal Processing

Cleans the signal of motion artifacts, electrical interference, and external noise.

  • Hardware filters
  • Bias circuits (RLD, ECG stabilization)
  • EMI isolation
04 / 09

Processing

Converts analog signals into structured digital data.

  • SoC (nRF54L15)
  • On-device edge computing
  • Sensor fusion logic
05 / 09

Memory

Stores physiological data for subsequent analysis.

  • SPI Flash memory
  • Ring buffer
06 / 09

Wireless Communication

Transmits data in real time to external devices.

  • Bluetooth Low Energy (BLE 5.4)
  • 2.4 GHz antenna
  • RF matching circuit
07 / 09

Power Management

Provides stable and efficient power to all system components.

  • Wireless charging
  • DC-DC conversion
  • Low-noise voltage regulators
08 / 09

Grounding & Noise Suppression

Prevents digital signals from interfering with the sensitive analog section.

  • Separate analog ground (AGND)
  • Single-point ground connection
  • Ferrite filtering
09 / 09

Mechanical Layer & Form Factor

Transforms complex electronics into a comfortable wearable device.

  • Behind-the-ear form factor
  • Contact sensors
  • Sealed enclosure
Blog

The instruments, the protocol, the literature.

Three threads sit underneath AORA: the clinical protocols used to induce and measure rumination, the behind-the-ear hardware stack that makes those measurements portable, and a fast-moving body of research pointing at EEG-in-a-wearable as the next interface.

  • 01
    Protocol

    How rumination is actually induced in a clinical EEG study.

  • 02
    Hardware

    What AORA Nano actually measures, behind the ear.

  • 03
    Literature

    The EEG-wearable research we're building on.
