Abstract: An implantable, wireless cardiac hemodynamics monitor system includes a bio-sensing module and a wireless electronic subsystem. The bio-sensing module is implanted in a heart or an artery of the mammal subject to continuously monitor cardiac functions of the mammal subject. The wireless electronic subsystem is implanted between a fat layer and a dermis layer of a skin of the mammal subject and electrically connected to the bio-sensing module through insulated flexible wires. the wireless electronic subsystem is wirelessly communicated to an external wireless power transfer (WPT) module and an external user interface module. In operation, the wireless electronic subsystem is used to wirelessly receive power transferred from the external WPT module, and provide the power to the bio-sensing module; and to obtain sensing signals of the cardiac functions monitored by the bio-sensing module, and wirelessly transmit the sensing signals obtained to the external user interface module.

Abstract: Hydrocephalus and shunt-related expenditures cost the US system over $2 billion dollars in annual expenses, with 125,000 shunt surgeries per year and an untreated mortality rate estimated at 50-60%. Existing diagnostics are expensive, inaccurate, and often harmful or invasive, and can lead to unnecessary admissions, further testing, or needless surgery. Collaborative efforts between Northwestern materials engineers headed by Dr. John Rogers alongside the leadership of neurological surgeons at Northwestern Memorial Hospital and Lurie Children's Hospital have produced and validated a noninvasive, thermal biosensor capable of diagnosing ventricular shunt malfunction.

Abstract: Provided herein are epidermal microfluidic systems and methods that allow for the collection of biofluids in a wet or aquatic environment, for example, from the surface of the skin. The described systems allow for the efficient collection of biofluids, without loss of the biofluid to the surrounding environment or introduction of extraneous liquids from the environment. The described microfluidic systems are versatile and can provide information regarding a number of biofluid properties both electronically and colorimetrically/visually.

Abstract: This invention relates to a soft, battery-free, flexible, non-invasive, reusable hydration sensor adherable to even small-areas and curvilinear surfaces of a body. The hydration sensor measures volumetric water content in skin as a function of depth, and wirelessly transmits data to a portable smart device. The hydration sensor includes a top layer for thermal, chemical and mechanical isolation of the hydration sensor from an environment; a bottom layer operably placed on a target area of interest on the skin; and a flexible printed circuit board (f-PCB) disposed between the top layer and the bottom layer. The f-PCB contains electronics for sensing and wireless communication. The bottom layer operably serves as a direct interface between the f-PCB and the skin and comprises a flexible adhesive for attaching the hydration sensor to the skin.
