Abstract

An apparatus for measuring the cutaneous electrical impedance of an individual, comprising an oscillator (10) operatively associable with a first skin portion (21) of the individual, and tuning means (11) for carrying out tuning of an oscillation frequency of said- oscillator (10) with a characteristic frequency of the nervous rete innervating the first skin portion (21), thereby obtaining a corresponding tuned frequency (f ). The apparatus (1) further comprises an output block (30) connected to the oscillator (10) to generate, as a function of the tuned frequency (f ), an output signal (31) representative of the electrical impedance (Zeq) of the first skin portion (21). Also described is a method of measuring the electrical impedance of an individual.
