From circuits to code

Why electronics drive better medical device software

In the development of medical devices, the integration of software and hardware is critical. A thorough  understanding of electronics is not just beneficial but often essential for software engineers at Zentis Medical. This knowledge bridges the gap between physical device functionality and software algorithms, ensuring accuracy, reliability, and safety in critical healthcare applications.

Why is this relevant?

Hardware-software synergy: Medical devices rely heavily on embedded software that interacts directly with hardware components. For instance, software in an insulin pump must precisely control the release of medication based on sensor readings. The understanding of how sensors, actuators, and microcontrollers behave, ensures that developers can create robust and efficient software. Real-time operating systems (RTOS), commonly used in medical devices, exemplify the need for this synergy, as they demand precise timing and hardware integration to meet strict healthcare standards.

Regulatory compliance and safety: Electronics knowledge facilitates  compliance with strict medical regulations such as FDA standards and ISO 13485. For example, the implementation of safety features like fail-safe mechanisms and hardware redundancy often requires a deep understanding of electronics to mitigate risks and ensure patient safety.

Zentis medical’s experience: Zentis Medical’s projects, such as the development of a new concept for an infusion pump development, exemplify the critical interplay between hardware and software. Achieving seamless communication between software algorithms and hardware components ensures accurate medication delivery, emphasizing the importance of electronics in software development.

Some might argue that software development can be abstracted from hardware considerations, especially with the rise of software as a medical device (SaMD), which often operates independently of physical hardware. But these applications rely more on ‘high-level’ programming and cloud-based solutions rather than hardware interactions.

While SaMD innovations have reduced the dependency on hardware knowledge for specific applications, embedded software in medical devices remains a cornerstone of healthcare technology. Comprehensive knowledge of electronics not only enhances development capabilities but also fosters innovation and ensures the highest standards of safety and reliability in life-critical devices. At Zentis Medical, this principle is at the heart of our commitment to advancing healthcare through integrated technology.
