The conductive claw

thingiverse

This project centers on minimizing interactions with communal surfaces primarily touchscreens such as ATMs and checkout displays. My design has undergone multiple iterations over the past few weeks, but I'm convinced that I've developed a simple and cost-effective solution that works effectively. The current design replicates the contours of a human finger when it comes into contact with a screen. The rounded tip, covered in metallic film, responds well to both resistive and capacitive surfaces. To create this device, start by printing the file and ensure that the tip is free of defects. Next, apply a layer of conductive tape to the outer edge of the claw extending back towards the user's finger. Aluminum foil tape has proven effective but tends to scratch unprotected surfaces. A better alternative is metallic vinyl that has been lightly sanded; it conforms well to the contours of the claw when subjected to gentle heat and doesn't damage screens. This device also opens door handles, presses buttons, and pushes objects.
