An auto-powered biosensor capable detecting a target molecule, and a method of powering the same, wherein the biosensor is fabricated with a microfluidics layer, a multimodal sensing layer comprising a biofuel cell and an electrode, and a logic circuit that may include a processor and non-transitory memory with computer executable instructions embedded thereon.

Systems, methods, and devices for measurement of the osmotic pressure of fluids and, more particularly, to improving the measurement accuracy and precision of the osmolarity of the tear film. The approaches described herein improves upon the existing art of tear film osmometry to provide better performance in the presence of environmental instability.

A system for collecting and utilizing health data can include collecting data relative to a patient's health and aggregating the data with other sources of data to define a database. The patient data can be collected using an electronic device, such as a smart contact lens or smart contact lens container. The data within the database can be manipulated, organized, or otherwise processed to determine trends, relationships, and other characteristics of the database. The characteristics of the database can be correlated to predict a health condition of the patient, generate a healthcare recommendation, or a combination thereof.
