Wearables

1. Overview

Maker/DIY Educational Wearables are programmable electronic devices designed for hands-on learning and prototyping in educational settings. These devices combine hardware components with software tools to enable users to create interactive wearable projects. Their importance lies in fostering STEM (Science, Technology, Engineering, Mathematics) skills, promoting creativity, and bridging the gap between theoretical concepts and practical applications. With the rise of IoT (Internet of Things) and edge computing, these wearables serve as foundational tools for teaching embedded systems, sensor integration, and data analysis.

2. Main Types and Functional Classification

Type	Functional Features	Application Examples
Microcontroller-Based Kits	Programmable cores (e.g., Arduino, ESP32), GPIO pins, breadboard compatibility	STEM projects, IoT prototyping
Programmable Sensors	Integrated IMU, temperature, light sensors with SDK support	Health monitoring, environmental studies
Flexible Wearable Platforms	Stretchable PCBs, textile-based circuits, e-textile compatibility	Smart clothing, interactive art
AI-Enabled Wearables	On-device machine learning, gesture recognition, voice processing	Gesture-controlled interfaces, adaptive learning systems

3. Structure and Components

Typical educational wearables consist of:

Microcontroller Unit (MCU): Central processing unit (e.g., ARM Cortex-M series) for executing programs
Sensors: IMU (Inertial Measurement Unit), biometric sensors, environmental sensors
Power System: Rechargeable LiPo battery (200-500 mAh), voltage regulators
Communication Modules: BLE 5.0, Wi-Fi (802.11n), NFC for data transmission
Output Interfaces: RGB LEDs, vibration motors, OLED displays
Physical Enclosure: 3D-printable cases or flexible TPU substrates

4. Key Technical Specifications
