Under the technological wave of "Internet of Everything", mobile phone cases are becoming an important carrier for innovative functions, and their technological integration has become a new indicator to measure the level of industry development. The popularity of wireless charging modules is the most significant functional breakthrough. The latest generation of magnetic charging case increases the charging efficiency to 15W through a 15-coil array design, and expands the tolerance of alignment error to ±3mm, solving the pain point of early products' "discharge when touched". The addition of sterilization function accurately hits the needs of the post-epidemic era. UV-C ultraviolet sterilization shell can kill 99.9% of E. coli within 30 minutes, and the repurchase rate of this type of product in maternal and infant population reaches 42%.
Aermy Technology's DIY ink screen phone case shows another path to innovation in functionality. It uses NFC dynamic refresh technology to control the data transmission distance within 3cm, which not only ensures connection stability but also avoids the risk of information leakage. Actual measurements show that the pattern switching response time is only 0.8 seconds, and the power consumption per operation is as low as 0.01mAh. Unlimited refreshes can be achieved by relying entirely on the NFC power supply of the mobile phone. What is more worthy of attention is the trend of functional fusion. The "health monitoring shell" launched by a certain brand has achieved basic indicator detection such as heart rate and blood oxygen; while the new version that Almi is testing will add a pressure sensor to display altitude and weather warnings. The superposition of these functions has enabled the mobile phone case to evolve from a "passive accessories" to a "active service terminal", and its technical content is no less than that of early feature phones.
