In the rapidly evolving landscape of healthcare, IoT wearable health tech devices are revolutionizing how we monitor and manage our well-being. These cutting-edge gadgets offer access to real-time health data that empowers regular users, patients, and healthcare providers alike. However, alongside their numerous benefits, these devices also bring a unique set of challenges that must be addressed to unlock their full potential, especially in remote patient monitoring. In this blog, we are going to explore seven key challenges facing IoT wearable health tech devices and discuss potential solutions to ensure they can deliver on their promise of a healthier future. So, let’s begin:

7 Challenges of IoT Wearable Health Tech Devices

1. Privacy and Data Security Issues

Wearables such as Fitbits and smartwatches collect a wealth of health data, including heart rate, sleep patterns, and physical activity levels. Yes, this data can provide valuable insights into your health, but such IoT solutions also pose significant privacy and security risks.

According to a recent study, nearly 6 in 10 respondents worry that their devices are vulnerable to security breaches. Imagine the consequences of a data breach exposing sensitive health information. It is more important for healthcare professionals to secure patients’ data, especially those who rely on wearables for personalized services. Invest in strong security measures to protect users’ health and data privacy.

2. Data Collection Inaccuracy for Remote Patient Monitoring

Do you think the data IoT wearable devices collect are 100% correct? For example, Apple Watches and Samsung Galaxy Fitbits are designed to track your steps, right? They also track heart rate and other health metrics. However, the accuracy of this data is questionable! For instance, a research review found that step counts can differ depending on where the device is worn. It’s true- as a result, it affects calculations of calorie burn, distance goals, and overall activity tracking.

So, you can get a general idea of activity levels, but it may not be accurate for healthcare services. Yes, there are high-tech wearable devices (usually prescribed by physicians) like oximeters, blood pressure monitor devices, etc. that can provide more accurate results. Enterprises that want to develop IoT wearable devices must choose the right IoT development services. It is crucial because the gadget and the app decide whether your product gives accurate results or not.

3. Battery Drain of the IoT Wearable Devices

One common issue with wearable digital health tech devices is their battery life. Many devices, such as Fitbits and samsung Bands, only last a few days on a single charge. This can be inconvenient, especially if you forget to charge your device and it runs out of battery mid day-workout.

The need for frequent charging can disrupt users’ routines and make them less likely to wear their devices consistently. This, in turn, reduces the effectiveness of the device in tracking and managing health metrics. However, manufacturers are working on the battery capacity to make healthcare technology user-friendly and long-lasting.

4. Lack of User Engagement

Even the most advanced wearables, like continuous glucose monitors (CGMs) or smart patches for sleep apnea, require consistent use to be effective. However, maintaining user engagement can be challenging! Studies show that the use of activity trackers is often abandoned after a few weeks or months, and only a little over 40% still use such devices after 24 months. 

For instance, forgetting to wear a CGM sensor could result in missing crucial blood sugar data. Incomplete data makes it difficult to manage health conditions effectively. So, it is a challenge to keep those users motivated and engaged with their devices. Here, engaging UI/UX design experts play an important role in ensuring continuous user engagment.

5. Integration Issues with Existing Health Tech

While wearables can track various health metrics, integrating this data with existing healthcare systems remains a significant challenge. Imagine your smartwatch tracks your sleep patterns, but your doctor cannot access this data. Yes, you can often find other challenges, like:

  • Many healthcare providers are not equipped to access or interpret the data from wearables. This gap means that even if patients diligently track their health metrics, their doctors may not be able to use this information effectively.
  • Wearable devices from different manufacturers often use various data formats and communication protocols. This lack of standardization makes it difficult to aggregate and analyze data.
  • Existing Electronic Health Records (EHR) systems may not be designed to handle the continuous and voluminous data from users.

So, for greater effectiveness, both manufacturers and IoT development companies should focus on the integration of the existing health care systems.

6. Higher Costs of Wearable Gadgets

High-tech wearables with advanced health features often come with a hefty price tag. Generally, IoT wearable devices can cost anywhere from $150 to well over $1000. Yes, this expense can be a barrier for many users! It limits the accessibility of this health technology. While wearables offer significant benefits, their high cost can prevent a large segment of the population from reaping these advantages.

7. Lack of Technical Support and Maintenance

Wearable gadgets need technical support and maintenance for critical healthcare. Brands must provide customer support that helps users troubleshoot issues, understand device functionalities, and receive timely assistance, enhancing their overall experience. Yes, there is a cost associated with it.

Besides that, regular updates to software and firmware are crucial. You need to create an app that offers easy maintenance procedures, such as seamless updates and user-friendly interfaces. Overall, it reduces downtime and ensures the wearables remain reliable. Effective technical support and maintenance build trust among the users.

5 Ways to Fix These Challenges in IoT Wearable Health Tech Devices

Now you know the common challenges, but is there any solution? You can consider the following five aspects for your IoT solutions:

  • Enhanced Encryption: Implement advanced encryption protocols to safeguard health data against breaches and unauthorized access.
  • AI-Driven Accuracy: Do not rely on traditional methods; make your device unique by utilizing machine learning algorithms to improve the accuracy and reliability of health metrics.
  • Efficient Firmware Updates: Consult IoT development services to develop streamlined, over-the-air update systems for seamless and user-friendly maintenance.
  • Integrated Health Platforms: Understand the target audience and create interoperable software solutions that enable wearables to seamlessly connect with existing health systems.
  • User-Centric Design: You need to focus not only on user-friendly gadgets but also on the app that runs on smartphones. Design your mobile app with engaging UI/UX to ensure success in this competitive industry.
