This is a repository for the prototype Stick&Slip device created by Alex Mazursky, Jacob Serfaty, and Pedro Lopes at the University of Chicago's Human Computer Integration Lab. Stick&Slip is a wearable approach to alter the friction of everyday objects using liquid coatings on the fingerpad!
Arduinocontains code for the microcontroller (ESP32).PCBcontains the KICAD files for our custom PCB.3D-printscontains models for the wearable droplet generator and bracelet (.stl files). These can be printed with most SLA printers.
To reproduce our experience, we include the KiCad files to manufacture our delivery mechanism. In addition to the PCB and included SMT components, the device uses a Seeeduino Xiao ESP32C3 and two mini peristaltic pumps (Takasago Fluidic Systems, RP-Q) connected to thin silicone tubing (ID = 1 mm; OD = 2 mm) via barbed connectors. Each tube is then connected to the droplet generator.
