Connected Care: Building Secure and Reliable IoT Medical Devices

The Connected Future of Healthcare 

The future of healthcare is connected. From wearable monitors that stream vital signs, to smart drug delivery systems that adjust treatment in real time, to platforms that allow clinicians to visualize patient data remotely — connectivity is transforming patient care. 

For executives, connected care offers clear benefits: improved outcomes, proactive intervention, and stronger patient engagement. But it also presents significant challenges. Medical IoT devices must be secure, reliable, power-efficient, and compliant with strict regulations. Without careful design, connectivity can create risks that threaten both patient safety and brand trust. 

At Boston Engineering, our Embedded Systems and Digital Solutions COEs specialize in creating connected devices that balance intelligence, security, and usability. By embedding IoT into the complete product development process, we help innovators bring connected care solutions to market confidently and efficiently.

The focus and discipline of DFX is a powerful tool if used as part of a broader strategic approach to developing product/process differentiation, and a sustainable advantage against competition. Involve Design for X in Strategy. Once your team has determined the focus of your strategy, place the focus of design on developing competitive advantage. 

At Boston Engineering, DFX is a core part of creating values during our product development process. We focus on several key DFX areas that align with our expertise:

• Design for Manufacturability (DFM)
• Design for Assembly (DFA)
• Design for Cost (DFC)
• Design for Testability (DFT)
• Design for Reliability (DFR)
• Design for Serviceability/Maintainability (DFS)
• Design for Usability (DFU)
• Design for Modularity (DFMo)

Case Example 1: Wearable Patient Monitoring Device

A client set out to create a wearable system capable of continuously monitoring patient vitals and transmitting data securely to clinicians. The challenge was delivering real-time insight while ensuring comfort, battery longevity, and data security. 

Boston Engineering delivered by: 

• Designing custom electronics and firmware optimized for low-power continuous monitoring. 

• Implementing secure Bluetooth and Wi-Fi protocols for reliable connectivity. 

• Encrypting data end-to-end to ensure HIPAA compliance. 

• Applying ergonomic design for patient comfort during extended wear. 

Outcome: The wearable provided clinicians with real-time patient data, extending care beyond the hospital and enabling early interventions that improved outcomes. 

Case Example 2:  Connected Drug Delivery System

Another innovator needed to modernize a drug delivery device by enabling connectivity and intelligence. The device had to administer precise doses, track usage, and share data securely with clinicians. 

Boston Engineering helped by: 

• Designing embedded systems to monitor device status and ensure accurate dosing. 

• Building firmware that logged and transmitted usage data to a secure cloud platform. 

• Integrating authentication and encryption protocols to safeguard patient data. 

• Coordinating with our Control Systems COE to ensure safety remained the top priority. 

Outcome: The connected drug delivery device enabled greater clinician oversight and patient safety, while creating a scalable platform for future connected therapeutics. 

AL & ML in Health Care - The Medical Workplace Multiplier

In this new Whitepaper, learn how AI and ML can enhance the medical workforce’s abilities and improve patient outcomes. 

While some view AI as a potential job replacement threat, the reality is that these advanced capabilities are better positioned as “workforce multipliers” that will amplify the abilities of doctors, nurses, technicians and other medical professionals.

Artificial intelligence and machine learning are emerging technologies that have immense potential to reshape healthcare delivery and medical practice.

Case Example 3: Remote Patient Data Visualization Platform

A medical innovator sought to build a remote visualization tool that consolidated patient monitoring data from connected devices into a usable dashboard for clinicians. The challenge was presenting complex data streams in a way that was secure, accessible, and actionable. 

Boston Engineering delivered by: 

• Developing data pipelines to aggregate information from multiple connected devices. 

• Designing visualization tools that simplified complex data for clinician decision-making. 

• Ensuring cybersecurity and HIPAA compliance across the platform. 

• Partnering with our Design for X COE to make the platform scalable for widespread adoption. 

Outcome: The visualization platform gave clinicians actionable insights in real time, enabling proactive care decisions and improving the efficiency of patient management. 

The Common Thread: Connected Devices + Complete Product Development

Across wearables, drug delivery systems, and data visualization platforms, the common challenge was not connectivity itself — but ensuring connectivity was secure, reliable, and clinically valuable. 

Boston Engineering ensures that connected devices succeed by: 

• Designing for cybersecurity and compliance from the start. 

• Optimizing for power efficiency in wearables and portable systems. 

• Applying systems engineering to integrate electronics, controls, software, and user interfaces. 

• Using digital solutions to simulate and test connectivity before physical builds. 

• Embedding DfX principles to ensure scalability and manufacturability. 

This holistic approach ensures that connected medical devices don’t just function — they deliver trusted, actionable insights at scale. 

Connecting Innovation to Better Outcomes 

For executives, the promise of connected care is compelling — but only if the devices are designed with security, usability, and reliability from the outset. Poorly designed connectivity can undermine adoption and create risks, but well-executed IoT devices can transform patient outcomes and business success. 

Boston Engineering has demonstrated its ability to deliver secure, reliable, and regulatory-ready connected devices across wearables, drug delivery, and remote monitoring platforms. By integrating connectivity into the complete product development process, we help innovators deliver solutions that connect innovation directly to better outcomes. 

When you partner with Boston Engineering, you gain more than an engineering service provider — you gain a trusted product development partner who knows how to build the future of connected care.
