There are 3 main directions in the application of zirconia ceramics in intelligent wearable equipment.
1.the most important use is ceramic mobile phone cover, since the introduction of the AppleWatch in 2015, for the first time using zirconia ceramics as cover appearance, leading the entire back of the trend of the market, at present, HUAWEI, millet mobile phone has a variety of ceramic cover, and substantial sales, not to be part of the ceramic cover mobile phone preferred.
2.use as fingerprints.
3. wearable equipment shell, is also the first source to AppleWatch, currently including Samsung, a variety of watches, bracelets are used zirconia shell, because of many advantages of zirconia ceramics: the first is to wear waterproof, secondly is not shielded signal, third is the appearance of zirconia ceramics after grinding and diamond shining.
