In recent years, high-sensitivity pressure sensors with flexibility, biocompatibility and stretchability have attracted widespread attention in the fields of wearable electronic devices and smart skins.

The high frequency transformer is the most important part of the switching power supply. The switching power supply generally uses a half-bridge power conversion circuit. When working, two switching transistors are turned on in turn to generate a 100kHz high-frequency pulse wave, and then the high-frequency transformer is used to step down and output low-voltage alternating current.

Transformers and inductors are easily confused because they have the same physical shape. There is only one rule that can be distinguished between them, the transformer is marked with "QTK", and the inductor is marked with "QHP".

As power systems worldwide transition toward smart grids, the demand for intelligent current transformers (CTs)—devices that combine traditional current measurement with advanced digital capabilities—is surging.

The smart grid represents the next-generation power system, integrating advanced sensing, communication, and automation technologies to enhance efficiency, reliability, and sustainability. A critical enabler of this transformation is high-precision current measurement, which underpins energy metering, fault detection, and dynamic protection.
