Physically unclonable cryptographic primitives are promising for securing the rapidly growing number of electronic devices. Here, we introduce a new class of physically unclonable primitives from layered molybdenum disulfide (MoS2) by leveraging the natural randomness of their island growth during chemical vapor deposition (CVD). We synthesize a MoS2 monolayer film covered with speckles of multilayer islands, where the growth process is engineered for an optimal speckle density. Using the Clark-Evans test, we confirm that the distribution of islands on the film exhibits complete spatial randomness, hence indicating the growth of multilayer speckles is a spatial Poisson process...

Adhesives used for continuous glucose monitoring (CGM) devices can cause skin irritations, which sometimes lead to abandonment of the therapy. A previous sensor manufacturing process involved two separate adhesives-one applied to the skin-facing surface of the fabric patch, and a second, ethyl cyanoacrylate-based adhesive, which secured the plastic transmitter housing to the superficial side of the patch. Our current process for attaching the transmitter housing to the fabric patch uses heatstaking, wherein the housing is heated and pressed against the patch with a specialized assembly apparatus...
