Disclosed is a system and method for performing measurements on a biological subject, and in one particular example, to performing measurements of analytes in a biological subject by breaching a functional barrier of the subject using microstructures, wherein the one or more microstructures include an aptamer for binding one or more analytes.

Novel tools and techniques for assessing, predicting and/or estimating effectiveness of fluid resuscitation of a patient and/or an amount of fluid needed for effective resuscitation of the patient, in some cases, noninvasively.

A wearable device configured to monitor physiological parameters of a wearer can include: a physiological parameter measurement sensor configured to monitor a plurality of physiological parameters; a hardware processor; a display in communication with the processor; and a band configured to secure the physiological parameter measurement sensor on a wrist of the wearer. In some implementations, the hardware processor is configured to: obtain a first plurality of signals from the physiological parameter measurement sensor when the band is secured on the wrist at a first tightness; determine a signal quality responsive to the first plurality of signals; and output an indication on the display to adjust tightness of the band with respect to the wrist from the first tightness to a second tightness based on the determined signal quality.

A wearable medication adherence monitoring (MAM) device for wearing by a patient, including an operating unit (OU) which includes: a wireless communications unit (WCU); a processing unit (CPU); a memory unit; and one or a plurality of peripheral interface(s) with a plurality of input peripherals; and further includes the plurality of input peripherals and output peripherals in a MAM unit (MAMU) which includes: an interactive visual display unit (VDU) including a visual display (VD) and a VD patient interaction (PI) tool (VDTOOL); and an interactive audio platform (AP) including an audio output unit (SPK) and an audio PI tool (MIC; and one or a plurality of sensor unit(s) (SU(s)) including at least one biomarker sensor, and optionally at least one biometric sensor; included in one or a plurality of attachment units (AU) for wearing of the device on or about a body part of the patient.

A non-invasive method and apparatus utilizing a single wavelength (800 nm, isobestic) for the instantaneous, reflective, non-pulsatile spatially resolved reflectance system, apparatus and mathematics that allows for the correct determination of critical photo-optical parameters in vivo. Transcutaneous blood constituent (analyte or drug level) measurements can be determined in real-time. The “closed-form” nature of the mathematics with inclusion of other wavelengths (660 nm and 1300 nm) and a non-invasive transmissive array allows for immediate calculation and real-time display of Hematocrit, Hemoglobin, fractional tissue blood volume (Xb), Hematocrit-Independent Oxygen Saturation, fractional tissue water content (Xw) and other pertinent blood/plasma values in a variety of handheld or other like devices.

A contact sensor and system for incorporation within clothing and other wearable items to monitor activity at a body surface. The sensor includes a contact membrane having a body surface contacting area and one or more base layers of knitted fabric. The base layer(s) is thicker over an area congruent with the body surface contacting area of the contact membrane. As a result, the contact membrane is urged into the forming of a raised outer surface for projection against a body surface.
