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.

  • 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.

さてここに、握る動作をするとどう反応するのか秘密が隠されていますーペアになっているセンサの半分は、Pixel 2 XLの横端を握るとこの動作を感知します。

センサはフレキシブルなプリント板回路基板で作られており、スチールのブロックでこの基板の両側を覆っています。そしてメタル製ビットの間の隙間を繋ぐようにひずみゲージが付けられています。

ひずみゲージは変形可能でセンシティブなレジスターで、握る動作をすると抵抗値がわずかに変動します。

スペーサーで分けられた2列のひずみゲージにより、このセンサーは単一のゲージストリップよりも高い解像度が得られ、わずかな歪みも検出することができます。

握る動作をすると、外側のゲージが短くなり、内側のゲージが長くなります。この動作がpixelのハードウェアに次の動作を引き起こすための
