Video: Smartphones and Mems
Choose the correct word.
1. Today’s smartphones have a built-in device that can detect / trace changes in orientation and tell the screen
to rotate.


2. The phone measures changes in gravity / mass with a chip in which engineers have created a tiny silicon
accelerometer.
3. Engineers determine changes in orientation by measuring the location / motion of the comb-like fingers
inside the accelerometer.
4. Engineers use some unique chemical formulas / properties of silicon to etch the accelerometer’s fingers
and H-shaped sections.
5. To make a pyramidal hole in silicon, scientists used potassium hydroxide which dissolves / distributes
silicon faster in the vertical than in the horizontal direction.
6. Engineers are able to create such complex structures as smartphone accelerometers because the process of
miniature technology has been automated / outdated.
