Wearable devices continuously collect large amounts of sensitive personal data, including health information and location, raising significant privacy concerns.12, 13 This data is often transmitted to cloud servers, making it vulnerable to breaches and unauthorized access if robust security measures are not in place.11 There are also concerns about how third-party applications might use collected data for targeted advertising or other purposes without explicit user consent.10
Another area of criticism relates to the accuracy and reliability of the data collected by consumer-grade wearable technology. While useful for general trends, these devices may not always provide clinical-grade precision, which can be problematic if users rely solely on them for critical health decisions.9 Battery life remains a limiting factor, often requiring frequent recharging which can deter continuous usage.8 Furthermore, the high cost of some advanced wearable technology can be a barrier to widespread adoption, particularly in healthcare settings where affordability is a key consideration.7 Addressing these concerns requires stringent data governance frameworks, improved cybersecurity protocols, and greater transparency from manufacturers regarding data collection and usage.
Wearable Technology vs. Internet of Things (IoT)
While closely related, wearable technology and the Internet of Things (IoT) represent different, though overlapping, concepts. The Internet of Things is a broad ecosystem of interconnected physical devices, vehicles, home appliances, and other items embedded with sensors, software, and other technologies, enabling them to connect and exchange data over the internet. IoT encompasses a vast array of devices, from smart home thermostats to industrial sensors and connected cars.
Wearable technology, on the other hand, is a specific category of IoT devices designed to be worn on the body. These devices are characterized by their direct interaction with the user and their ability to collect personal data, such as biometric information or activity levels. Therefore, all wearable technology can be considered part of the larger Internet of Things, but not all IoT devices are wearable. The distinction lies in the form factor and direct personal application: IoT is the overarching network of connected objects, and wearable technology is a personal subset within that network.
