From: Touch, press and stroke: a soft capacitive sensor skin
Fabrication of the sensor. (A) Step 1: Mold. Mold filled with Ecoflex™, with the square pillars that will form the top surface of the skin shown at left and the X-shaped supporsts that form the bottom layer shown at right. (B) Step 2: Pattern electrodes (black) using carbon black-Ecoflex™ composite by doctor blading through a shadow mask. (C) Spin on encapsulating layer to prevent external electrical contact. (D) Step 3: Bond layers using a thin layer of uncured Ecoflex™ which glues the square pillars to the base layer.
