Client Overview
Dotcom IoT LLP, in collaboration with leading healthcare innovators, developed a biomedical wearable patch aimed at continuous and non-invasive health monitoring.
The objective was to create a compact, reliable, and patient-friendly solution for real-time tracking of vital health parameters.
Business Need
There is a growing demand for real-time, remote, and continuous patient monitoring, especially for early diagnosis, wellness tracking, and post-operative care.
Healthcare providers required a wearable device that could:
> Track key vitals like temperature, SpO₂, heart rate, and posture
> Operate wirelessly and comfortably on the body
> Communicate securely with a smartphone application for real-time health analysis
> Support over-the-air firmware upgrades to enhance functionality over time
Dotcom Contribution
Designed and developed a Bluetooth-enabled biomedical patch that senses:
> Body temperature
> SpO₂ (blood oxygen level)
> HRM (heart rate monitoring)
> Body posture/movement- Utilized ARM Cortex-M4 for low-power, high-efficiency embedded processing.
- Implemented ZephyrRTOS for reliable real-time operation across multiple sensors and BLE communication.
- Built-in BLE 5.2 module for stable and energy-efficient wireless communication with Android devices.
- Developed a companion Android application to receive, log, and analyze physiological data in real-time.
- Integrated OTA (Over-the-Air) firmware update support for remote bug fixes and feature enhancements.
