Web Bluetooth SDK for ORPHE INSOLE
ORPHE-INSOLE.js
Build browser prototypes with ORPHE INSOLE pressure, motion, and orientation data. ORPHE INSOLEをWeb Bluetooth経由で扱い、足裏圧とモーションを使ったWebアプリを作れます。
What is ORPHE INSOLE?
Smart insole data, ready for web prototypes.
ORPHE INSOLE is a smart insole with pressure sensors and an IMU for real-time foot movement measurement. ORPHE-INSOLE.js connects that stream to browser apps through Web Bluetooth.
Foot pressure and motion in one stream
Use pressure values together with converted acceleration and gyroscope values for gait, balance, sports, and rehabilitation experiments.
No native app setup for early tests
Open the examples in Chrome or Edge, connect with Web Bluetooth, and start inspecting live packets.
Compatible with existing ORPHE style APIs
Use new Orphe(...) or the clearer new OrpheInsole(...) alias while keeping familiar callbacks.
Official product details
A pressure and motion platform inside the insole.
The official ORPHE INSOLE pages describe a replaceable smart insole that measures foot pressure and motion in real time, connects with apps or external devices, and supports smart-shoe prototyping.
Each foot includes six pressure sensors plus 3-axis acceleration and 3-axis gyroscope data.
Store-listed ranges for acceleration, gyroscope, and pressure measurement.
Sampling rate may vary depending on the application and mode.
The store lists magnetic connector charging and wireless charging with a separately sold ORPHE MAT.
US Men's sizes 3.5 to 9.5 are listed, with 7.5 marked unavailable and more sizes planned.
The evaluation kit page mentions TestFlight app distribution, raw data recording, and open-source Python and JavaScript libraries.
The official store currently presents ORPHE INSOLE β as an Evaluation Kit for approved customers and research partners, including three pairs of insoles and an iOS application.
What data can I get?
Pressure, motion, and orientation callbacks for browser apps.
The library parses INSOLE SENSOR_VALUES packets and routes values into callbacks you can use directly in UI, games, visualization, and data logging tools.
Pressure values
Receive foot pressure samples and packet metadata for balance, loading, and contact timing.
Acceleration
Use converted XYZ acceleration values for movement intensity, step timing, and interaction design.
Angular velocity
Track rotational motion from the foot-mounted sensor without writing your own BLE parser.
Quaternion
In default mode 4, receive orientation values together with pressure and motion data.
Recognition and use cases
Designed for real movement data, from sports to safety research.
PR TIMES states that ORPHE INSOLE was selected for CES 2026 Best of Innovation and highlights sports and fitness, biomechanics and AI datasets, and industrial work-safety applications. This SDK page focuses on the browser layer for inspecting and prototyping with the raw pressure and motion stream.
Quick Start
Connect one ORPHE INSOLE and print pressure data.
Include the CDN build, create an OrpheInsole instance, call setup(), and start the default streaming mode with begin().
| Mode | Data stream |
|---|---|
4 |
Gyro, acceleration, pressure, quaternion. Default for begin(). |
3 |
Gyro, acceleration, pressure. Use begin({ streamingMode: 3 }). |
1 |
Legacy real-time sensor values for compatibility tests. |

Choose the entry point that matches your test.
Use the dashboard for live inspection, the terminal for raw packet checks, and the API reference when you are ready to wire the data into your own app.
Sensor Dashboard
Connect one or two ORPHE INSOLE devices and inspect pressure, motion, quaternion, and left/right assignment.
Terminal
Read and write BLE characteristics, watch raw SENSOR_VALUES bytes, and export captured values.
API Documentation
Browse generated JSDoc for the ORPHE INSOLE class, callbacks, BLE methods, and parser helpers.
What you can build
Prototype around the use cases ORPHE INSOLE is built for.
The product story centers on foot-pressure visualization, motion analysis, smart-shoe applications, and research-grade data collection. ORPHE-INSOLE.js gives web developers a direct way to explore those signals.
Pressure and posture feedback
Inspect pressure and foot-motion changes for running, training, coaching tools, and performance experiments.
Biomechanics datasets
Record synchronized pressure and motion streams for validation, exploratory analysis, and AI dataset creation.
Work-safety inspection
Explore fall, slip, trip, and fatigue-related motion signals before connecting them to larger safety systems.
Device inspection
Build dashboards for device state, packet health, left/right assignment, and data stream debugging.
Beta notice
ORPHE-INSOLE.js is currently provided as a beta library.
Documentation and tutorials are still being improved. For hands-on validation, start with Chrome or Edge on a desktop environment and an ORPHE INSOLE device.
