在Android设备上使用指纹扫描仪的电容信息

[英]Capacitance information using fingerprint scanner on android device

I've done a great amount of research, searched through API's, and looked through the forums for an answer. 我进行了大量研究,搜索了API,然后在论坛中寻找答案。 Finally decided to join stackoverflow! 终于决定加入stackoverflow!

THE PROBLEM: 问题:

I want to get the capacitance of the finger through a piece of hardware on the phone. 我想通过电话上的一块硬件来获得手指的电容。

POSSIBLE SOLUTION: 可能的解决方案:

I've come to the conclusion that, although the phone uses a capacitive touch screen, accessing the capacitance information on the touch screen is not possible (unless somebody knows how to?). 我得出的结论是,尽管电话使用电容式触摸屏,但无法访问触摸屏上的电容信息(除非有人知道该怎么做?)。 I've considered using the fingerprint scanner, being that it is a capacitive sensor (the fingerprint scanner on the S5). 我考虑过使用指纹扫描仪,因为它是电容式传感器(S5上的指纹扫描仪)。 Is there any way to access only the capacitance value instead of the image from the fingerprint scanner? 有什么方法可以只访问电容值,而不访问来自指纹扫描仪的图像?

Some phones or tablets embed fingerprint sensor and a SDK to obtain template (list of minutiae) or picture. 一些电话或平板电脑嵌入了指纹传感器和SDK,以获取模板(详细信息列表)或图片。 SDK also provide method to enroll and match. SDK还提供了注册和匹配的方法。
