Abstract: The system is comprised of an interface (1) consisting of one or more electrodes capturing electromyographic (biolectric muscle activity) signals, an earphone/microphone and a radiofrequency transmitter/receiver; a nexus module (2), with means for the encoding and interpretation of the electromyographic signals which taking into account both their duration as well as their amplitude and time lapse interval, wirelessly connected to the transmitter/receiver of the interface (1); and a controller (3), consisting of means for controlling and managing the devices comprising the ambient intelligence environment of a domotic, inmotic, military or other types, the input of which is connected to the output of the nexus module (2). Additionally, the communication facilitated by the earphone/microphone is completed with glasses incorporating a device capable of projecting visual messages on the inner side thereof.

Abstract: The invention relates to a method, to a device for electronic characterization, and to a measurement cell and support for monitoring a chemical or physical process with results that can be assessed in terms of the weight variation of a coating deposited on a piezoelectric sensor, exposed to a fluid medium with stable physical properties. The invention uses the deduction of an analytic expression establishing a simple connection between the phase variation of a fixed-frequency signal, which queries the piezoelectric resonator, and the variation in the bulk density of the coating. The invention is suitable for implementations that use piezoelectric resonators for characterizing biochemical and electrochemical processes, such as, inter alia: piezoelectric biosensors and immunosensors, process and material characterization by AC electrogravimetry, detection of dissolved chemical or biological substances.
