问iphone5s 用的是什么类型的指纹传感器

半导体的 是苹果自己收购的指纹厂家的指纹传感器

半导体  使用的是苹果收购的AuthenTec公司基于TruePrint技术的半导体指纹传感器以下为引用A unique semiconductor-based fingerprint technology that uses small RF signals to detect the fingerprint ridge and valley pattern. The RF electronic imaging mechanism (TruePrint technology ) works by reading the fingerprint pattern from the live, highly-conductive layer of skin that lies just beneath the skin's dry outer surface layer.
