What Actidot can provide

Start with the data you need and the result you want to review. Select the hardware, firmware and application together.

01 · Sensor platform

Actidot V4

Three-axis acceleration and temperature acquisition, on-device storage and Bluetooth transfer. A compact, reusable platform for healthcare applications and research development.

02 · Applications

Choose a defined workflow

BraceSense, Actidot-710 and M2810 are downstream applications or products. Their supported devices, firmware and outputs are specified individually.

03 · Customer outputs

V4 is preparing for launch. Contact us for sample availability and delivery timing. Battery life and recording duration depend on the data mode. Development interfaces and the scope of open-source support are agreed for the selected version.

Activity-recording applications & reports

Step records, product-defined intensity categories, and examples of single-leg or bilateral reports.

High/low step categories describe acceleration-based product outputs. They do not directly measure joint load, plantar pressure or metabolic intensity. Report interpretation depends on the application and version.

The historical M2810, M710 and M710bi resources remain labelled separately below. M710bi illustrates left–right comparison. Their names do not establish a firmware mapping to Actidot-710. WeChat QR codes open the named mini programs; they are not native App download links.

Activity insights across care settings

These are settings in which activity records may be discussed or illustrated. A listed condition does not establish a validated clinical claim for Actidot. Begin with one defined recording and reporting task.

About

Shanghai Hongyah Sports Technology Co., Ltd. is a project company under HD Data Technology, specialising in Actidot.

Founded in 2021 and based in Shanghai, Hongyah focuses on rehabilitation, chronic care and physical activity. Actidot V4 provides acceleration and temperature recording, on-device storage and Bluetooth transfer; each application determines the resulting records and reports.

Record is the starting point. Reminder and Relief express the 3R development direction; availability and any clinical benefit must be assessed for the specific product and version.
