A more practical example is that of the watch shown in Figure 3.4. This watch is intended to be suitable for underwater use. In order to prevent water from penetrating into the watch around the stem, the stem is equipped with an elastomeric O-ring. It is quite difficult to determine if this O-ring is in the correct position and undamaged from a radiograph (Figure 3.3). This is because the radiographic image is almost entirely determined by attenuation in the steel watchcase and stem.†

Smartwatches are wearable smart phones in the form of wrist watches having small monitors, which can perform a variety of functions, including connecting to the Internet.3 Similar to wrist watches, these provide user friendliness.4 Smartwatches are often connected to peripherals to enable active interaction with devices.5 They also provide information in the background and can provide additional information because they have sensors attached.4,6 It is possible to continuously integrate computer processing through smartwatches and process the desired information without restriction of place and time.7 Smartwatches also have the advantage of freeing users’ hands.8 These features make smartwatches suitable as wearable computing devices.9 A study by the Consumer Electronics Association also found that wrists are the most suitable body parts to wear wearable devices.10
