A stretchable sensor is provided. The stretchable sensor includes a first stretchable electrode including a first elastomer and a first conductor dispersed in the first elastomer, a stretchable active layer formed on the first stretchable electrode and including a third elastomer and an ion conductor dispersed in the third elastomer, and a second stretchable electrode formed on the stretchable active layer and including a second elastomer and a second conductor dispersed in the second elastomer. The stretchable sensor is effectively capable of sensing a temperature without being affected by strain and recognizing strain without being affected by temperature.

A multi-laminar electrospun nanofiber scaffold for use in repairing a defect in a tissue substrate is provided. The scaffold includes a first layer formed by a first plurality of electrospun polymeric fibers, and a second layer formed by a second plurality of electrospun polymeric fibers. The second layer is combined with the first layer. A first portion of the scaffold includes a higher density of fibers than a second portion of the scaffold, and the first portion has a higher tensile strength than the second portion. The scaffold is configured to degrade via hydrolysis after at least one of a predetermined time or an environmental condition. The scaffold is configured to be applied to the tissue substrate containing the defect, and is sufficiently flexible to facilitate application of the scaffold to uneven surfaces of the tissue substrate, and to enable movement of the scaffold by the tissue substrate.

An apparatus for automatically separating hair follicles includes a follicle separating unit configured to cut a skin tissue of a scalp cut from a back of a head of an alopecic patient in units of follicles and to classify follicles by a number of hairs included in each follicle in an incisional hair transplant or to classify follicles each directly extracted from the back of the head of the alopecic patient by the number of hairs included in each follicle in a non-incisional hair transplant, and a follicle separation control unit configured to control an operation of the follicle separating unit.

Systems, instruments, and methods for minimally invasive procedures including one or more of fractional resection, fractional lipectomy, fractional skin grafting, and/or fractional scar revision are described. Embodiments include instrumentation comprising a scalpet assembly coupled to a carrier, and the scalpet assembly includes a scalpet array. The scalpet array includes one or more scalpets configured for fractional resection, fractional lipectomy, fractional skin grafting, and/or fractional scar revision. The system includes a vacuum component coupled to the scalpet assembly and configured to evacuate tissue from the a site. The carrier is configured to control application of a rotational force and/or a vacuum force to the scalpet assembly.

The present invention relates to a novel acellular artificial skin substitute or scaffolds comprising biopolymer and bioactive components and the process of preparing said artificial skin substitute. The novel artificial foam-based skin substitute scaffold of the present invention addresses the problems in the prior art by providing a biocompatible, biodegradable, Non-immunogenic, non-irritant and a cost-effective scaffold.
