Hexoskin Developer Platform

Build With Physiological Data

Build products and research pipelines on raw ECG, respiration, and movement from Hexoskin and Astroskin. Hexoskin OneSDK streams the signals live to your Android app, Hexoskin OneAPI serves every synchronized recording to your servers, and Hexoskin OneSync decodes recordings locally when data must stay on site.

Choose the Integration Layer

Hexoskin OneAPI

Server-side REST access to every synchronized recording: raw signals, data channels, and metrics, in JSON over OAuth. Feed analysis pipelines, data warehouses, and custom dashboards in Python, R, or any language.

Hexoskin OneSDK

An Android library for your own application. Stream raw ECG, thoracic and abdominal respiration, and three-axis acceleration live from Hexoskin and Astroskin recorders, with heart rate, breathing rate, and ventilation, and control sessions, stored recordings, and firmware.

Hexoskin OneSync Local Decoding

Keep recordings on your own computer or server. OneSync decodes the raw signals and the data channels computed on the recorder locally, without sending data to the Hexoskin server, for restricted data environments.

What Hexoskin OneSDK Streams

OneSDK gives your application the signals the sensors record, live from each recorder, with the processed channels, signal quality, and device status on the same timestamp, as listed in the Hexoskin and Astroskin data specifications.

Astroskin

ECG
Three leads · 250 Hz · 16 bits
Respiration
Thoracic and abdominal RIP · 125 Hz
Acceleration
Three axes · 50 Hz · ±16 g
Optical Signal
PPG · 75 Hz
Heart Channels
Heart rate (30 to 220 bpm) every second
Breathing Channels
Breathing rate (2 to 90 rpm) and minute ventilation, every second
Movement Channels
Step count and cadence, every second
Oxygen and Pressure
SpO₂ and a systolic blood-pressure estimate (60 to 260 mmHg), every second

Heart rate quality, ECG, respiration, PPG, and blood-pressure sensor status, and data-loss flags
Device Status
Recording state, garment connection, battery state, and battery percentage
Device Control
Start and stop sessions, annotations, stored recordings, clock, identification, and firmware

OneSDK runs on Android 8.0 or later and connects to the recorder over Bluetooth Low Energy or USB. HRV, sleep, energy expenditure, and profile-adjusted ventilation are computed after synchronization and delivered through Hexoskin OneAPI.

Why Developers Build on Hexoskin

Raw Signals, Not Only Scores

Build on the waveforms themselves: ECG, thoracic and abdominal respiratory inductance plethysmography, and three-axis acceleration, with every derived channel on the same timestamp. Your algorithms see what the sensors recorded.

Proven in Research and in Orbit

Hexoskin and Astroskin appear in 325+ scientific publications, and Astroskin has been used aboard the International Space Station since 2018. Build on a platform with a published record.

One Stack, From Prototype to Product

Prototype with the standard Bluetooth heart-rate profile of the Hexoskin recorder, build the product on Hexoskin OneSDK, and run the back end on Hexoskin OneAPI. Hexoskin OneView and Hexoskin OneApp cover the study team and the participants.

Scope the Data Workflow

Tell us about the product, the users, and where the data needs to go. Every study and organization runs on Hexoskin OneSuite. Hexoskin OneAPI and Hexoskin OneSDK are licensed per project and per year, with paid developer hours available for integration support. Our team can recommend the tools and the license scope.
