ID: 95143

Description: Since HTC U11 released, it has won lots of...

Steps:

  1. Eight Strain Gauge, two ways to access
    2. Step image Step image
  2. First, for easier opening, we need to heat up the mobile frame. Please be aware of the glass cracks while heating and opening.
    3. Step image Step image Step image
  3. We could see that there’s more glue on its frame than other phones’, this should be the reason why it can meet the requirement of IP67, to be used under water, such as taking photos while swimming or diving.

  4. Then we reach to the part Camera
  5. Finish the main part Teardown
    6. Step image Step image
  6. Here we head to the frame, it seems like there is a module on both sides of the frame

  7. A full Teardown
  8. A close-shot of the module
  9. As we could see the pictures showing that each side of the frame has a module (which we did not see on other mobile devices). It has thin structure but strong and stable signal.

  10. Based on the Teardown works above, we came to a conclusion, that is, Edge Sense is an "8 super-thin strain gauge” with 4 pairs of sensors on each module that separately installed on both sides of the U11 frame.
  11. These strain gauges are to detect the force changing while pressing, then the signals transmitted to the CPU of mobile devices for processing, and forming a signal output.
  12. It could recognize long press, short press and different level of pressure.
  13. It is not by recognizing the contact of skin (or we can say not by recognizing the Capacitive sensing) while squeezing to activate this function, but by detecting the pressure of pressing to start it. Otherwise how can we initiate the Edge Sense functions underwater or when we are wearing gloves?
