- 摘要：
- In a fiber quality sensor (S) comprising a first pair of electrodes, the first pair of electrodes include a first conductive electrode (1), and a first dielectric electrode (D, 2) having a first dielectric material (D) with a conductive backing (2). The fiber quality sensor (S) may further comprise a second pair of electrodes, the second pair of electrodes including a second conductive electrode (1), and a second dielectric electrode (D, 2) having a second dielectric material with a conductive backing, wherein in a tribo-electric series of materials, the material of the conductive electrode is arranged between the first and second dielectric materials. The fiber quality sensor (S) may comprise horizontally or vertically alternating first and second pairs of electrodes. The first and/or second pairs of electrodes may be tilted, slanted and/or zigzag-shaped. The fiber quality sensor (S) may for the or each pair of electrodes further comprise an amplifier coupled to the pair of electrodes and having an input impedance exceeding 1 T©, and preferably being 200 T©. The fiber quality sensor (S) is advantageously applied in a hair care device.
