crucial design consideration for wearables is **comfort and ergonomics**.**Water and Sweat Resistance**: Wearable devices intended for fitness, sports, or outdoor activities should be water and sweat-resistant to withstand exposure to moisture and maintain comfort and functionality in various environmental conditions.**Sensory Experience**: Designing wearables with smooth edges, rounded corners, and ergonomic contours can enhance the tactile experience and minimize pressure points or discomfort caused by sharp edges or uneven surfaces.**Heat Dissipation**: Wearable devices that generate heat, such as smartwatches or fitness trackers with built-in sensors and processors, should incorporate mechanisms for heat dissipation to prevent discomfort or overheating during use.Adjustable straps, bands, or clasps can help users customize the fit to their preferences, ensuring a snug and secure fit without being too tight or restrictive.**Fit and Adjustability**: Wearable devices should be designed to fit a wide range of body sizes and shapes comfortably.2.3.4.5.6.7.
