摘要
A method and a sensor (1) for the generation of pulsed signals biomimetically coding sensorial information.The method is based on the combination of chemical - physical phenomena able to produce a pulsed signal of electrical and/or optical nature coding an external stimulus through variations in the pulse frequency. The frequency/amplitude content of these pulsed signals codes the external stimuli by qualitatively and quantitatively reproducing what occurs in biological sensorial systems. The stimulus coding occurs through the modulation of an heat flux (H) drawn from the external environment (2), thereby avoiding the need of a dedicated energy supply.The sensor operating according to this method transfers the external thermal energy to the inside of a chamber (5,32,49,66) thereof containing a fluid whose pressure acts, through a window section (5a,32a,49a,66a) variable with the external stimulus (S), on a vibrating member (10,29,45,67) generating the pulsed signal. Thus the signal frequency is variable as a response to the stimulus intensity.
