Fig. 1: Fabrication and demonstration of a sensorized Y/V plasty tissue model.
From: Sensorized tissue analogues enabled by a 3D-printed conductive organogel
In a Y/V plasty, a Y-shaped incision with the vertex located at the site of unwanted tissue is cut into the dermal layer, and the flap in the skin layer is pulled down and sutured into a V shape after excision (a). A sensorized Y/V plasty tissue suturing pad (b) is fabricated by encapsulating a conductive organogel and conductive thread electrodes within the skin layer of the pad. This organogel is 3D-printable (c) and visually imperceptible in the skin layer of the pad (d). The strain sensor located in the skin flap demonstrated a clear response to the elongation experienced by the flap during suturing (e).
