Nowadays, prosthetic field has seen many accomplishments and success by the use of different technological advanced techniques. Prosthetic hands are made out of very high-quality materials but at the same time they are very expensive. There are different techniques available for designing prosthetic hand but most of these techniques have some problems; they are extremely expensive, very hard to install and may require operative surgery before using them. Most of the amputees who require upper limb amputation do not prefer to go for highly expensive prosthesis despite of their high quality. Therefore, the idea is to introduce the initial design of an EEG based controlled smart prosthetic hand which can be treated as customised solution. In our approach we controlling prosthetic hands by the brain waves, obtained from an electroencephalography (EEG) headset. The EEG-based headset (Mind wave Mobile) designed by Neurosky is used to communicate with human brains. The device tries to resemble like natural hand movement as the brain part is involved in it. The movement of biological neuroprosthetic hand by signal acquisition through neurosky headset. The brain waves are sensed by sensors in the neurosky headset and then this signal is processed by the processing system which detects the different levels of attention and meditation through headset. When the system detects that the attention meter value indicates the high attention level it gives command signal to the servo motors so it drives forward, and hand starts closing. If an amputee wants to open the hand to release an object, he/she needs to be in relaxing position and that in turn reduces level of the attention meter value. It senses by control system and that gives command to servo motor which move backward and close hand. According to the level, hand movement can be generated. It is used for an amputee below the elbow.
