MINDD by Ybrain is a non-invasive neuromodulation system for depression treatment to improve a patient´s mental health. The headband uses transcranial direct current stimulation to deliver a stream of electricity to the frontal lobe, a specific brain area. As soon as the electric waves are passing the area where decreased activity is associated with depression, users feel a tingling. The device can be connected to a smartphone app for sleep logging, exercise and medical treatment. Because of its wearable design, the treatment can be done in hospitals and at home.
