Raw biosignals after the E4 era
Open API, exportable data, EDA, PPG, temperature, motion, and a lower-friction hardware path.
Use cases
One platform. Every field that measures the human body.
OpenPulse is not sold as one generic fitness product. It is configured around a pilot: the signals, the environment, the data path, and the partner's workflow.

Pilot segments
Filter by the partner you want to convince.
Objective layers for workplace stress assessment
EDA and HRV context for consultants who already run surveys and interviews.
Human signal plus environment signal
Gas, temperature, heart-rate context, and local alarms in one configurable band.
Response measurement without a black box
EDA and HR pipelines for consumer research, stimulus testing, and controlled response studies.
White-label recovery without device lock-in
Configured bands for premium recovery, stress, and retreat experiences.
Biosignals as input for installations
Turn pulse, motion, EDA, and environment into live media control signals.
The secondary market that builds with you
For data-sovereign users, developers, and quantified-self people who hate sealed clouds.
Where the fit is sharpest
The strongest markets do not want another watch. They want a measurement layer.
OpenPulse becomes interesting when the partner already has a workflow, but the existing wearable hardware is too closed, too generic, or missing one key signal.
01 / Research
Raw biosignals without the black box.
For labs, OpenPulse is a configurable raw-signal wristband: EDA, PPG, temperature, motion, documented processing, and exportable data for repeatable pilots.

Why now
The E4 gap
With the Empatica E4 retired, research teams still need inspectable wearable biosignals without moving into a closed consumer ecosystem.
02 / Safety
The worker and the environment in one timeline.
A gas spike means more with body context. A physiological spike means more with environmental context. OpenPulse can join both into local alerts or exports.

Configuration
Body module + environment module
One wristband can monitor worker context and ambient hazards instead of splitting the pilot across separate devices.
Stress assessment gets a repeatable signal layer.
EDA and HRV context for consultants who already run interviews, workshops, and surveys.
EDAHRVExport
Explainable reaction signals for stimulus testing.
EDA and pulse pipelines synchronized to media, retail, or product-testing stimuli.
EDAPPGSync
A white-label recovery layer, not a locked watch account.
Configured guest experiences for recovery, stress trends, and resort-owned workflows.
PPGTempEDA
Biosignals as live input for light, sound, and space.
MQTT outputs turn pulse, EDA, motion, or environment into a control surface.
PPGMotionMQTT
For the people who already want to build their own wearable.
Data-sovereign users, quantified-self builders, and open-source developers who hate sealed clouds.
Open APIGitHubNo lock-in
Pilot fit
Bring one concrete measurement problem.
OpenPulse is strongest when a partner has a clear question: what signal, on whom, in which context, and what decision should the output support?
