Abstract: Disclosed herein are recombinant spider silk compositions formed from a silk-based extrudate, such as stable films that adsorb to the skin, and methods for making these compositions. In some embodiments, provided herein is a method of making a silk-based emulsion, comprising: mixing a composition comprising a recombinant spider silk polypeptide powder and glycerol by applying pressure and shear force to the composition, thereby transforming the composition to an extrudate; suspending at least a portion of said extrudate in an aqueous solvent to form an aqueous extrudate suspension; and mixing said aqueous extrudate suspension into an emulsion to form said silk-based emulsion.

Abstract: A system may include an electronic device that communicates with one or more wearable tags. The wearable tags may be placed on different parts of a user's body or clothing and may be used for one or more health-related functions such as posture monitoring, sun exposure monitoring, physical therapy, running assistance, fall detection, and other functions. The wearable tag may have different types of sensors that gather different types of sensor data depending on the health-related function that the wearable tag is being used for. A user may configure, control, and receive data from the wearable tag using an electronic device. The electronic device may be used to determine the location of the wearable tag on the user's body and to determine the desired health-related function for the wearable tag based on user input or based on sensor data gathered from the wearable tag.
