HandY is a bionic hand developed by one of our researchers from the BISITE research group. This prototype has been developed as a practical and useful alternative for controlling hand and foot prostheses through the muscles of people who have lost their limbs. They are controlled by a system which has a muscle-computer interface. In this case, the bionic hand has a series of motors which move the five fingers independently. In addition, sensors and electrodes are located over the skin, they measure the surface electricity which is produced when muscles are contracted (surface electromyography). The designed system measures the surface electricity on the skin, it interprets it and generates the movement of the motors which cause the hand to move.

The cost of the system is low in order to make it accessible to a large number of people, it has been created using a simple electronic system and 3D printing. This last feature allows to highly personalize the product since each person will be able to redesign and reprint their own prosthesis and adapt it to their likes and needs. Lastly, this prosthesis allows to configure different types of movements which can be adapted to each individual and specific circumstances. All of this makes this product a great development in the field of bionic prosthesis. Its developer, Ramiro Sánchez Torres, continues working on the project in order to provide the users of these prostheses with more features. I would like to congratulate him for his ideas and fantastic work and I wish him great success.
