Unit
- Definition: Wearable technology includes electronic devices that can be worn on the body as accessories, implants, or clothing. These devices often integrate sensors, processors, and wireless connectivity to provide real-time data collection and feedback.
- Historical evolution: Early wearable computers from the 1960s and 1970s were bulky and research-oriented. The modern era began with Bluetooth headsets and fitness trackers in the 2000s, followed by smartwatches and smart glasses in the 2010s.
- Core characteristics: Wearables are portable, hands-free or minimally intrusive, and provide continuous monitoring or context-aware services. They require low power consumption, small form factors, and robust connectivity.
- Categories: Common categories include fitness trackers, smartwatches, smart glasses, smart clothing, hearables, and medical wearables. Each category targets different use cases and user interactions.
- Key applications: Health monitoring (heart rate, steps, sleep), fitness tracking, navigation, notifications, augmented reality, and industrial safety. Medical wearables include continuous glucose monitors and ECG patches.
- Design constraints: Wearables must be comfortable, lightweight, and durable. They face challenges in battery life, thermal management, and user acceptance. Industrial design plays a crucial role in adoption.
- Market landscape: The global wearable market is growing rapidly, driven by health awareness, aging populations, and advances in sensor technology. Major segments include consumer, healthcare, and industrial.
- Future trends: Emerging trends include flexible electronics, smart fabrics, augmented reality glasses, and implantable devices. Integration with AI and cloud computing enhances functionality.
- Power management: Battery life is a critical constraint for wearables. Developers use low power microcontrollers, energy efficient wireless protocols like Bluetooth Low Energy, and energy harvesting techniques such as kinetic or solar charging to extend usage between charges.
- Connectivity standards: Wearables commonly use Bluetooth, Wi Fi, NFC, and cellular IoT technologies. Choosing the right protocol depends on the device's data transmission needs, range, and power budget. Emerging standards like Matter enable cross platform interoperability.
- User interface design: Due to small screens or no screens, wearables rely on voice commands, haptic feedback, gesture recognition, and touch interfaces. Designers must prioritize glanceable information and minimal user input while ensuring accessibility for diverse users.
- Regulatory and compliance: Medical wearables require FDA or equivalent regulatory approval, involving rigorous clinical testing and quality management systems. Even non medical devices must comply with regional radio frequency emission standards and data protection laws such as GDPR or HIPAA.
Security Consideration
MEDIUM RISK
Vulnerability: Data Privacy Leakage - Wearable devices collect sensitive personal data such as health metrics, location, and biometrics.
Mitigation: Implement data encryption at rest and in transit, enforce user consent mechanisms, and provide transparency in data collection policies.
