In the last years, the fast spread of tablets and smartphones has led to deep changes in the used of technology, even in the medical devices field. Flexibility, ease in communication and in data exchange, small sizes and product customization are the goals that medical devices manufacturers have to reach in order to achieve competitiveness. Even in the EEG/PSG field there is a strong request of more and more sophisticated devices with small dimension, in order to maximize the patient comfort and to operate in a non “invasive” but effective way. This speech aims to present the choices and the solutions adopted in the development of a electrophysiological signals acquisition (and storage) medical device. First of all, the impressive size and weight of the device, 10 times smaller and higher than the devices commonly used in the EEG/PSG field. The second focus is on the use of wireless transmission based on Bluetooth “Low Energy”, which significantly reduces the power consumption. The third aspect is related to the ability of the device to communicate with the iPad/iPhone by Apple, that is one of the main icon of the technological, cultural and social revolution of the moment.
