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 The hand makers do not publish theirs.

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

- polyester sheet, silver-filled conductive ink
- Comes out
- sheet with printed conductor lines
- Equipment
- screen printer
- 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.
Detail
- Goes in
- printed sheet, semiconductive ink
- Comes out
- sheet with sensing layer
- Equipment
- screen printer
- 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.
Detail
- Goes in
- two printed sheets, adhesive
- Comes out
- tactile sensor array
- Equipment
- laminator
- Why it matters
- The grid is what lets one thin film report where it is touched as well as how hard. · our reading
