Systems for applying a transcutaneous monitor to a person can include a telescoping assembly, a sensor, and a base with adhesive to couple the sensor to skin. The sensor can be located within the telescoping assembly while the base protrudes from a distal end of the system. The system can be configured to couple the sensor to the base by compressing the telescoping assembly.

Embodiments of devices and methods for evaluating tissue are disclosed. In one embodiment, a method for measuring a characteristic of a tissue may include passing a current through the tissue, measuring a signal corresponding to the voltage resulting from passing the current through the tissue, analyzing current passed through the tissue and resulting voltage to determine the electrical characteristics of the tissue; and analyzing the electrical characteristics of the tissue to determine a status of the tissue. Methods for achieving relatively constant sensor application pressure are disclosed.

A sensor includes a sealing tape having a first folding line and a second folding line, and an electronic component adhered to a middle area between the first folding line and the second folding line. A first side area of the sealing tape is folded along the first folding line and adhered to the middle area to cover the electronic component. A second side area of the sealing tape is folded along the second folding line and adhered to the first side area to hermetically wrap the electronic component in the sealing tape.

A muscle anti-clenching training device comprising a flexible device body conformable in a range of configurations upon a user’s body, and including: a skin-contact side and a top cover side; electrical contacts mounted in the flexible device body and exposed upon the skin-contact side; an adhesive upon the skin-contact side; an alert device mounted in the flexible device body; sensing circuitry electrically connected to the electrical contacts and structured to monitor an electrical property in a user’s body; and an electronic controller coupled to the sensing circuitry and structured to activate the alert device to produce an alert signal where the monitored electrical property is indicative of a muscular contraction.

Embodiments of apparatuses and methods for determining an emplacement of sensors in a wound dressing are disclosed. In some embodiments, a wound dressing includes a plurality of sensors configured to measure wound or patient characteristics. One or more processors are configured to receive wound or patient characteristics data as well as emplacement data. The received data can be used to determine an emplacement of the plurality of sensors, the wound dressing, or a wound. The sensors can include a set of nanosensors. The wound dressing can include pH sensitive ink which can be utilized for determining a placement of the wound dressing and determining a pH associated with the wound. The wound dressing can be used in a negative pressure wound therapy system.

The present it relates to a sensor applicator assembly for a continuous glucose monitoring system and provides a sensor applicator assembly for a continuous glucose monitoring system, which is manufactured with a sensor module assembled inside an applicator, thereby minimizing additional work by a user for attaching the sensor module to the body and allowing the sensor module to be attached to the body simply by operating the applicator, and thus can be used more conveniently. A battery is built in the sensor module and a separate transmitter is connected to the sensor module so as to receive power supply from the sensor module and be continuously used semi-permanently, thereby making the assembly economical. The sensor module and the applicator are used as disposables, thereby allowing accurate and safe use and convenient maintenance.
