Electronic devices to be waterproofed can be classified as follows,

(1) Underwater (freshwater, seawater, other liquids)
(2) Equipment that can be immersed in water
(3) Where it can be exposed to droplets (water in the vicinity of the place of Continue reading →

This time, I will talk about wearable devices for healthcare/sports.

With the rise in health consciousness and the development of sensors, materials, and information technology, the development and commercialization of wearable devices has become more active. Wearable devices first became popular in Europe and the United States, and then quickly became popular in Japan as well.

As the demand for IoT devices such as wearable devices and outdoor sensors increases, the waterproof design of electronic devices is required more and more.

A waterproof design is much more difficult than one thinks and hard to deal with. It’s not uncommon to have a hard time identifying water leakage points, which is the most important part of a waterproof trouble-shooting. In addition, it’s not uncommon that cost-effective measures can not be found.
