Gelatin: a skin phantom for bioimpedance spectroscopy

Phantoms mimic the properties of tissues, like skin. The electrical response of a skin phantom should be similar to the electrical response of an in vivo skin tissue. In this work the electrical characterization of gelatin based skin phantoms and of different skin sites are presented. The bioimpedance measurements of the gelatin based phantoms are compared with in vivo skin measurements, demonstrating that gelatin has potential as the basis material for the fabrication of low-cost skin phantoms for bioimpedance spectroscopy.
