Capacitance imaging of the skin surface

Abstract

Capacitance imaging is a necessary tool for both completely describing and quantifying skin surface hydration.

In vivo skin imaging for hydration and micro relief-measurement

“…One of them is the non optical skin capacitance imaging using sensors based on silicon technology primary developed to sensing fi ngerprints for security reasons (2,7,11,13). The analysis paper proves a signifi cant linear correlation between the results obtained by Corneometer device (taken into consideration as reference value for skin hydration) and the averaged parameters measured by SkinChip® (1,7,12).…”

“…The scientifi c laboratories L´Oréal (Paris, France) in cooperation with ST Microelectronics (Geneva, Switzerland) modifi ed the chip technology for fi ngerprint sensor and developed a device enabling to get the image of skin surface -SkinChip® (1,6,7,8). On a similar principle, we modifi ed the chip technology for fi ngerprint sensor (commercially manufactured as SPF200-USB fi ngerprint sensor) and developed a device able to imaging skin surface which extends the existing diagnostic and therapeutic procedures in pathological conditions infl uencing micro-relief and skin hydration.…”

Sweat Gland Awakening on Physical Training: A Skin Capacitance Mapping Observation

“…Over the past decade, an innovative progress afforded the Skin Capacitance Mapping (SCM) method representing a specific type of nonoptical skin surface imaging [4][5][6][7]. This method relied on fine-tuned electrometric measurements of the skin surface properties.…”

“…Such electrometric assessments of the upper layers of the epidermis represented a convenient noninvasive way for assessing the SC hydration. Such properties are closely related to a series of specific SC structures and functions [6][7][8][9].…”

“…In normal conditions, the epidermis over a large part of the body produces a tidy Stratum Corneum (SC) composed of 15-20 layers or so of corneocytes with a total thickness of about [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] µm. This part of the epidermis is continuously renewed from the granular layer, and the outermost corneocytes gradually desquamate from the surface [1].…”
