Medical Devices and Data

Technology to Instrument the Body and its Interpretation

The miniaturization of electronics has driven innovation in medical instruments. This text asks: how do these new instruments work, how do they interpret their data, and when do they err? It also identifies key factors driving innovation. This text is accessible for anyone who would like to understand non-invasive medical instruments.

The miniaturization of electronics has driven a huge innovation in medical instruments. Medical-grade systems are now able to be sent home with patients, alongside small, portable devices for monitoring sports performance, stress, and lifestyle.

The core ideas behind these devices originated about 130 years ago, but they are now made cheaply and are readily available in consumer devices like smart watches, as well as in new diagnostic instruments.

Medical Devices and Data: Technology to Instrument the Body and Its Interpretation focuses on three key questions: How do these new instruments work? How do they interpret their data? And when do they err? It also identifies the key factors that are driving this innovation further.

This text is written for those who would like to understand non-invasive medical instruments in more detail. It is written in an accessible manner, and no formal background in science, engineering, or medicine is required. Some equations are used where necessary, but calculus is avoided. This book explains the key ideas behind the advanced techniques used.

Key features:

• Explores the design and use of medical instrumentation, seeking to explain the data measured and how it relates to body processes
• Discusses what these devices mean: modern instruments give a whole range of indications: from basic (heart rate) to much more complicated (sleep quality score). For users of these devices, this book hope to shed some light on the information available
• Details when results can be trusted and how to cast a critical eye over the accuracy and interpretation of these instruments
