Aora — power up your mind
POWER UP YOUR MIND
What Aora measures.
Cognitive Load
A real-time read of how hard your brain is working right now. Built from validated self-report and passive sensing.
Neural Recovery
How well your brain is recovering between deep-work sessions. The signal your HRV can't see.
Burnout Risk
An early-warning trajectory built from the Copenhagen Burnout Inventory and continuous wearable data.
How it works.
Nine independent layers, synchronized in real time — each purpose-built to capture, process, and deliver cognitive state without compromise.
Sensor Layer
Reads raw biological signals from the body.
- ECG electrodes
- PPG sensors (blood flow, SpO₂, HR, HRV)
- Multispectral LEDs
Analog Front-End
Converts extremely weak biosignals into measurable electrical data.
- Ultra-low-noise amplifiers
- Signal conditioning circuits
- Analog ECG/PPG processing
Filtering & Signal Processing
Cleans the signal of motion artifacts, electrical interference, and external noise.
- Hardware filters
- Bias circuits (RLD, ECG stabilization)
- EMI isolation
Processing
Converts analog signals into structured digital data.
- SoC (nRF54L15)
- On-device edge computing
- Sensor fusion logic
Memory
Stores physiological data for subsequent analysis.
- SPI Flash memory
- Ring buffer
Wireless Communication
Transmits data in real time to external devices.
- Bluetooth Low Energy (BLE 5.4)
- 2.4 GHz antenna
- RF matching circuit
Power Management
Provides stable and efficient power to all system components.
- Wireless charging
- DC-DC conversion
- Low-noise voltage regulators
Grounding & Noise Suppression
Prevents digital signals from interfering with the sensitive analog section.
- Separate analog ground (AGND)
- Single-point ground connection
- Ferrite filtering
Mechanical Layer & Form Factor
Transforms complex electronics into a comfortable wearable device.
- Behind-the-ear form factor
- Contact sensors
- Sealed enclosure
Measure the one thing you can't afford to lose.
Your cognitive state,
wherever you work.
No hardware required. Start with the software.
The AORA Chrome extension brings Cognitive Load, Neural Recovery, and Burnout Risk into every tab — running entirely in your browser. It's the software version of AORA, ready to use today.
A quiet nudge when you're about to start deep work in a recovery window. A green light when you're primed. Pair with the AORA Nano for continuous biosignal tracking — or use it on its own. No page content leaves your device.
