Single project 17/17

Drupro is a feedback system that allows the user to imitate a feeling of the hand. DruPro is able to partially emulate pressure sensation and can be easily customized through a modular design.

The glove is only used as an example for this project and is optional for prosthesis users. The pressure sensors are glued to the back of the glove or prosthesis with double-sided adhesive tape or similar aids. The fingertip is glued to the front of the pressure sensor to enlarge the pressure point. The assembled circuit board is clicked into the board holder and then attached to the back of the glove or prosthesis with double-sided adhesive tape.

The source of power is a simple powerbank, which is attached to the forearm. For easy attachment the powerbank we used, had a centering device, which was sewn onto the glove. Optionally the powerbank can be fixed to the prosthesis with double-sided adhesive tape.

The individual components are connected with cables, which are soldered to the respective components. The vibration motors are glued to the hook-and-loop tape with the adhesive side or double-sided adhesive tape to increase the adhesive strength and positioned in a way most comfortable for the user. The hook-and-loop tape can be shifted in order to find the most useful position for the user.

More details about the project can be found in the wiki of the HRW FabLab:

“Embedded Systems” was developed as part of the Emscher-Lippe-hoch-4 project. On the project website of Emscher-Lippe-hoch-4 you will find more detailed information about the project as well as an overview of all results from “Embedded Systems”:
