Abstract: Implementations of a wearable physical characteristic monitoring (PCM) device can include a substrate including two or more electrical traces, the two or more electrical traces being formed as laser-induced graphene (LIG) in a starch-based material layer, a sensor that provides a signal responsive to physiological characteristics of a patient wearing the PCM device, a processing system that provides physiological characteristics data based on the signal, and a communications system that enables communication of the physiological characteristics data from the PCM device, wherein the two or more electrical traces connect one or more of the sensor, the processing system, and the communications system.

Abstract: An identification mark and a method for manufacturing the identification mark is disclosed. The method includes providing a block of mycelium and integrating an NIR florescent dye into a surface of the block to define a first pattern in the surface of the block of mycelium. Once the NIR florescent dye is inserted, the NIR florescent dye is allowed to dry. Thereafter, the block of mycelium with dried NIR florescent dye is compressed into a thin sheet of mycelium leather and the compression results in distorting the shape of the first pattern into a second pattern. The created second pattern is the identification mark readable by the NIR camera and an illumination source.

Abstract: Implementations of the present disclosure discloses a system and skin-based sensor platform to monitor biochemical activity of a wearer. The system includes an apparatus for monitoring biochemical activity of a wearer, wherein the apparatus includes a base substrate layer including a carbon-based material having one or more laser induced graphene (LIG) fabricated elements. The one or more LIG fabricated elements include an inductor-capacitor circuit to receive a wireless signal and to provide passive wireless readouts, and one or more sensing circuits electrically coupled to the inductor-capacitor circuit to detect biochemical activity associated with the wearer of the apparatus. The apparatus further includes an adhesive layer provided on a first side of the base substrate layer to provide adhesion to the skin of the wearer, and an encapsulation layer placed on an opposing side of the base substrate layer.
