Part of the humanoid robot

Tactile sensor

Pressure sensor arrays in the fingertips and the palm, so the hand feels what it holds.

The step · Hand

Pressure sensor arrays in the fingertips, finger pads and palm; Figure built its own after finding the market's sensors would not last. Output: tactile sensor array: fingertip reading 3 g (Figure 03); 33 sensors, 10 g to 2,500 g (Dex3-1).

How it is made3 steps

polyester sheet, silver-filled conductive inktactile sensor array

One kind of tactile sensor, as its maker's engineers describe it. The hand makers do not publish theirs.

  1. 1

    Printing the conductor lines

    Parallel lines of silver-filled conductive ink are screen-printed onto a thin polyester sheet.

    Why it matters
    Screen printing lays down every line of the sensor in one pass, so a large area costs little more than a small one. · our reading

    Printing the pressure-sensitive layer

    A second ink, one whose electrical resistance changes when it is squeezed, is printed over the conductor lines.

    Why it matters
    This ink is the sensor: the harder it is pressed, the more easily current passes through it.

    Laminating two sheets into a grid

    Two printed sheets are laid face to face with their lines crossing and glued together around the sensing area. Each crossing becomes one pressure point.

    Why it matters
    The grid is what lets one thin film report where it is touched as well as how hard. · our reading
