Systems, devices and methods are disclosed for addressing body conditions, monitoring body conditions and adapting treatment of internal and/or external body conditions.

A blood glucose tracking system and method measures emitted microwave energy transmitted to and accepted by blood vessels in a desired target area of a patient in order to determine, in real time and in vivo, appropriate blood glucose levels. A measurement unit comprises a transmitter operatively connected to an antenna to deliver energy towards appropriate subcutaneous blood vessels. The measurement unit determines an accepted energy power value in the blood vessels associated with the desired target area. This measurement energy power value is compared with a calibration value, and the difference is used to determine a resultant blood glucose value. The determined blood glucose value may further be acclimatized using additional sensed values compensating for biological and ambient factors relevant to the patient. The final determined blood glucose value can be displayed for reading and/or transmitted and stored for recording for further reference.

Systems and methods for processing sensor data and self-calibration are provided. In some embodiments, systems and methods are provided which are capable of calibrating a continuous analyte sensor based on an initial sensitivity, and then continuously performing self-calibration without using, or with reduced use of, reference measurements. In certain embodiments, a sensitivity of the analyte sensor is determined by applying an estimative algorithm that is a function of certain parameters. Also described herein are systems and methods for determining a property of an analyte sensor using a stimulus signal. The sensor property can be used to compensate sensor data for sensitivity drift, or determine another property associated with the sensor, such as temperature, sensor membrane damage, moisture ingress in sensor electronics, and scaling factors.

In one embodiment, the pliable band body has a size and shape suitable for wrapping around an individual appendage and that includes an opening that leads to a cavity within the band body suitable for accumulating an amount of water and a band sensor embedded within the band body in communication with the cavity.

A sample capture and transport unit comprises a housing defining a substrate chamber for containing a sample-capture substrate. The housing comprises at least a first part and a second part which are movable relative to one another i) from a first closed configuration in which the substrate chamber is inaccessible; ii) to a first open configuration in which access to the substrate chamber is enabled to allow capturing of a skin-print on a sample-capture substrate contained within the substrate chamber; and subsequently iii) into a second closed configuration in which the substrate chamber is again inaccessible. The unit further comprises a retaining mechanism for retaining it in the second closed configuration. The retaining mechanism is disablable to permit movement of the unit out of the second closed configuration. A sample can be obtained at a first location, secured for transport and analysed at a second location.

A sensing system utilizing a multifunctional fabric provides capabilities of self-monitoring and monitoring the ambient environment before using the sensing fabric, and consequently, the system can determine whether the fabric is operating properly before using the fabric. The system can continuously provide information for determining a previous sensing result as well as continuously monitoring a signal of interest. If a problem occurs in any interval, the system can notify a user or a monitoring center of the problem, and resolves the problem so as to provide an uninterrupted monitored signal, achieving full-time monitoring. As a result, it is not required to frequently replace the sensing fabric, resulting in an environmental friendly effect. More importantly, the system has an energy generation mechanism and can conserve the energy. The system is applicable to a human being or animal. The monitored items include: a heartbeat, breathing, temperature, perspiration, blood pressure, blood oxygen, posture, gait, excretion, bleeding detection, and others. A pattern or body paint can be applied to the skin to serve as a transmission line or electrode, or provide an insulation effect, or provide an effect of discharging static electricity. The system on the fabric can interact with it. In other words, the two can operate in parallel. This also serves as a backup. Moreover, static electricity on bodies, fabrics, shoes, and chairs can be monitored, and the static electricity can be removed even stored. An electrostatic effect can be utilized to attract the fabric to a body and measure a physiological signal. Also, electricity can be generated by magnetic induction. The system is applicable in entertainment and leisure, and can be used to identify human being or animals.
