Here it is, the secret to the squeeze—half of the pair of sensors responsible for detecting when you squeeze the edge of your Pixel 2 XL. The sensor consists of a flexible printed circuit board wrapped around both sides of a line of steel chunks, with strain gauges bridging the gaps between the metal bits. Strain gauges are deformation-sensitive resistors, that slightly change their resistance when stretched or squished.
  • Here it is, the secret to the squeeze—half of the pair of sensors responsible for detecting when you squeeze the edge of your Pixel 2 XL.

  • The sensor consists of a flexible printed circuit board wrapped around both sides of a line of steel chunks, with strain gauges bridging the gaps between the metal bits.

  • Strain gauges are deformation-sensitive resistors, that slightly change their resistance when stretched or squished.

  • Having two rows of strain gauges separated by spacers should give this sensor higher resolution than a single strip of gauges would, allowing it to detect even the slightest of deflections.

  • As you squeeze, the outer row of gauges should be shortened, while the inner row is lengthened. This gives the Pixel software a larger absolute deflection to detect and measure to trigger the feature.

这就是挤压边框操作的秘密——这对传感器的一半可以感应你是否在挤压你的 Pixel 2 XL 的边框。

这个传感器由一个柔性印刷的,包裹在一条钢条周围的拥有连接金属元件缝隙的压力感应器的电路板中。

压力感应器是一个形变感应电阻,挤压它时的微小的形变都能改变其电阻。

跟一条压力传感器相比,两排用定位格架分开的压力感应器能让传感器有更好的表现,让其可以感应到很细微的改变。

当你挤压的时候,外侧的传感器会变短,同时内侧传感器会变长。这让Pixel的软件检测到一个很大的确定的偏移并且触发对应功能。
