Various embodiments provide multi-layered self-healing materials, capable of repairing puncture damage. The multi-layered self-healing materials, capable of repairing puncture damage of the various embodiments may be constructed by sandwiching a reactive (e.g., oxygen sensitive) liquid monomer formulation between two solid polymer panels, such as a polymer panel of Barex 210 IN (PBG) serving as the front layer panel and a polymer panel of Surlyn® 8940 serving as the back layer panel. The various embodiments may provide methods to produce multi-layered healing polymer systems. The various embodiments may provide a two-tier, self-healing material system that provides a non-intrusive capability to mitigate mid to high velocity impact damage in structures.

A light-weight radiation protection panel comprising radiation protection layer and a flexible material. The radiation protection layer comprises a plurality of a shielding material distributed in repeated and adjacent units of geometrical shapes, the light-weight radiation protection panel being able to be embodied in a wearable garment providing flexibility.

A tactile feedback glove for use in an extravehicular activity (EVA) environment by an astronaut is described. The tactile feedback glove is formed by a glove having an outer layer, a second layer and inner bladder, wherein the inner bladder encloses a gas environment suitable for an astronaut's hand. A force sensor is attached to a fingertip of each finger of the glove on an inner surface of the outer layer to sense the pressure applied at the associated fingertip. A haptic feedback device is attached to the fingertip of each finger of the glove on an outer surface of the inner bladder. Each haptic feedback device is adjacent to each associated force sensor and positioned to provide tactile feedback for the associated finger. A visual feedback device is also attached to an outer surface of the outer layer of the glove in a visual field of the astronaut. A controller receives a signal from each force sensor indicative of the force applied by the wearer at the associated fingertip, and sends a feedback signal to drive each haptic feedback device and the visual feedback device to provide tactile and visual feedback to the wearer when the signal from one of the force sensors meets preprogrammed levels.
