A non-invasive tool for skin disease diagnosis would be a useful clinical adjunct. The purpose of this study was to determine whether visible / near-infrared spectroscopy can be used to non-invasively characterize skin diseases. In-vivo visible- and near-infrared spectra (400-2500 nm) of skin neoplasms (actinic keratoses, basal cell carcinomata, banal common acquired melanocytic nevi, dysplastic melanocytic nevi, actinic lentigines and seborrheic keratoses) were collected by placing a fiber optic probe on the skin. Paired t-tests, repeated measures analysis of variance and linear discriminant analysis were used to determine whether significant spectral differences existed and whether spectra could be classified according to lesion type. Paired t-tests showed significant differences (p<0.05) between normal skin and skin lesions in several areas of the visible / near-infrared spectrum. In addition, significant differences were found between the lesion groups by analysis of variance. Linear discriminant analysis classified spectra from benign lesions compared to pre-malignant or malignant lesions with high accuracy. Visible / near-infrared spectroscopy is a promising non-invasive technique for the screening of skin diseases.

The invention provides a flexible skin surface dry electrode and a preparation method thereof. The flexible skin surface dry electrode comprises a flexible conducting substrate and multiple microneedle bodies forming a microneedle array, wherein each microneedle body is of a taper shape and comprises a root part and a front end, the root parts of the multiple microneedle bodies are fixed on one surface of the flexible conducting substrate, and the front ends of the microneedle bodies are higher than the surface of the flexible conducting substrate. According to the invention, the substrate material of an original dry electrode is changed from a rigid material into a flexible material; since the flexible substrate can be tightly attached to the skin, the microneedles on the dry electrode overcome the influence of keratoderma, the electrical contact characteristic of the electrode and the skin is improved and the contact impedance is reduced; when an external force acts on the dry electrode, the flexible substrate can generate elastic deformation, thus the breaking of the microneedles is effectively avoided and the use safety is improved; and the substrate material of the dry electrode with the flexible substrate is elastic, thus the wearing uncomfortableness is alleviated.
