LoRa-Enabled Smart Armband for Muscle Activity Monitoring

Design Concept

The device is a wearable armband that integrates muscle activity sensors with a LoRa communication module, designed specifically for stroke rehabilitation and athletic performance monitoring.

The goal is to capture muscle movement data, process it locally, and transmit it wirelessly over long distances for analysis, feedback, and therapy tracking.

Core Components

1.Flexible Strap (TPU material/Elastic cloth)

• Adjustable, lightweight, and skin-friendly
• Provides comfort for prolonged use in rehabilitation or sports.
• Acts as the base platform for sensor and module integration.

2.Sensor Modules (3 units or 2 units )

• Small, rectangular ABS housings.
• Could contain surface EMG electrodes (to measure muscle electrical signals) or IMUs (to track motion/orientation).
• Placed at strategic positions along the strap to capture localized muscle activity.

3.LoRa Communication Module (Slightly larger enclosure housing)

• Microcontroller for processing (Wio Tracker L1 E-ink)
• LoRa transceiver for long-range wireless communication.
• E-ink based display and control buttons for user interaction.
• Positioned on one side of the strap for easy access.

Design Language

• Color: White strap and sensor casings for a medical/clinical look (clean and professional).
• Form: Slim, ergonomic, with rounded edges for comfort and safety.
• Style: Minimalist but functional, balancing aesthetics with durability.
• Interface: Physical buttons with optional small display, so patients or therapists can quickly check device status.

Functional Workflow

• Strap is worn on the forearm or upper arm.
• Sensors detect muscle activation patterns (via EMG or motion).
• Data is sent to the LoRa module, processed, and transmitted wirelessly.
• Clinicians/therapists receive real-time data for:

1. Tracking patient progress in stroke recovery.

2. Monitoring muscle fatigue and performance in athletes.

3. Providing feedback for improved rehabilitation exercises.

Applications

• Stroke Rehabilitation: Remote monitoring of muscle recovery, helping therapists design better personalized programs.
• Athletics & Training: Tracking performance, muscle usage, and fatigue in real time.
• IoT Healthcare: Integration into remote patient monitoring systems for hospitals or home care.
