12. Key Challenges & Barriers

Wearable Technologies has penetrated to our daily lifestyle to an extent that its role complementing our healthy management cannot be neglected. Studies is being carried out to analyse and minimise the extent of side effects of wearable technologies. Although side effects of wearable is yet to be documented and discussed in detail on technological front, however certain aspects at the outset can be attributed to both behavioural or technical.

Health Anxiety

Although no substantial evidence of negative outcomes of wearable technologies is reported, however as these smart wearables highly influence behavioural pattern of an individual, there is high probability of development of health anxiety. Consistent monitoring of health metrics in absolute scenarios can create an unwarranted panic situation for an individual. Thus, this data needs to be corroborated with other health metrics like – age, time of day, physical exertion, or routine etc. These wearable devices are helpful for preventive medicine but data must be interpreted wisely and with consultation from a physician.

Inaccuracy Of Data

Data inaccuracy due to sensor reporting or device malfunctioning can also lead to inappropriate decision making for certain immediate concerns that might need critical attention. Like in case of overexercising or overeating. Place of usage of these devices on different parts of the body can also cause variability in data capturing which can also report inaccurate data. Factors like smart textiles, device fitting, and skin conditions can affect data collection. Wearable accuracy depends on placement, physiology, and movement. Wrist-based sensors may show 15% error, while ankle sensors offer better precision. These factors must be considered for trustworthy health insights.

Inaccuracy of wearable device can be majorly attributed to the placement of wearable sensors on the part of the body. Placement of device on Ankle is reported to be highly recommended leading to minimal error. Smart Ring or NFC rings is considered highly reliable for tracking vital signs just because of its presence on fingers.

Here’s the list of Mean Absolute Percentage Error Level based on the placement of Sensor on Human Body as per the American Journal of Public Health and studies reported in the New York Times

Following table elaborates the kind of error you can expect from the fitness tracker / Smart watches.

Electromagnetic Field (EMF) Exposure To Human Body

These smart wearable devices generally follow standard prescribed EMF threshold values, however, consistent exposure or over exposure of human body to EMF can lead to severe pain, nausea. Today’s modern lifestyle has left human body to tremendous exposure to EMF. EMF energy arriving at the human skin is dominated by the distance between the EMF emitting device and the skin. Consistent exposure to electromagnetic fields (EMF) from wearables can, in rare cases, cause discomfort, though most devices conform to safe EMF levels. Though within safety limits, some users report symptoms like dizziness. Continued research is needed for long-term impact evaluation.

Data Privacy

Data Privacy is one of the major concerns for these wearable devices. Smart wearables collect sensitive health data often stored in the cloud. Lack of standardized privacy regulations raises concerns about unauthorized access and data misuse. No such stringent data privacy guideline is laid out to keep check on data leakage, if any. Data privacy remains a significant concern.

13. Opportunities & Emerging Trends

As devices evolve, they are expected to incorporate personalized healthcare features such as genomics, allowing for predictive care and health insights based on individual DNA profiles. However, with this growing sophistication comes the need for ethical innovation—including robust regulations on biometric tracking, data privacy, and user consent. In conclusion, smart wearables are transforming into essential tools for personalized, proactive health management. Understanding their potential, limitations, and ethical implications empowers users to harness their benefits responsibly.
