Abstract: Intraoral sensors and associated systems, devices, and methods are provided. In some embodiments, an intraoral sensor for sensing pH within an intraoral cavity of a subject includes a film composed of a biocompatible polymer and a pH-sensitive molecule. The pH-sensitive molecule can be configured to change in color based on a pH within a subject's intraoral cavity. The pH-sensitive molecule can be immobilized in the film. The intraoral sensor can also include an adhesive configured to couple the film to a surface of a dental appliance or a tooth of the subject.

Abstract: Apparatuses and methods for monitoring wear status of a dental appliance may include a sensing module that sensing the temperature and one or more additional modalities (e.g., capacitance, impedance, pressure force) around a dental appliance to track when the user is wearing or not wearing the dental appliance. These sensing modules may also determine compliance more accurately with a dental treatment plan.

Abstract: Pressure sensor modules adapted for use with a dental appliance may include one or more pressure sensors encapsulated within a sealed cavity in which one or more walls of the sealed cavity are deformable so as to transduce pressure from outside of the cavity, due to deformation or movement of the dental appliance and/or the environment around the dental appliance, including the environment within a patient's mouth when wearing the dental appliance. Also described herein are method of making and using these apparatuses to identify and/or monitor the dental appliance, a patient condition and/or an orthodontic treatment. Also described herein are methods and apparatuses for identifying and/or characterizing sleep apnea using these pressure sensor modules.

Abstract: Oral sensing apparatuses and methods for recording and tracking physiological parameters (e.g., intraoral temperature) over extended periods of time. These apparatuses can be part of an oral appliance, such as (but not limited to) an aligner, retainer, night guard, palatal expander, attachment, etc., or it can be made as a standalone device that can be directly attached to one or more teeth or an oral appliance. Also described herein are methods of extended monitoring of a subject intraoral temperature for a variety of different clinical and non-clinical applications.

Abstract: Methods and apparatuses are disclosed for electronic devices associated with monitoring a patient's use of an intraoral dental appliance. The monitoring electronics may communicate with near-field communication (NFC) signals. An NFC booster is disclosed to improve NFC data transfer between the electronic devices that monitor patient usage and communication devices. NFC boosters may be included within dental appliance cases and/or mobile phone cases. Also described are method and apparatuses for mounting the monitoring electronics onto the dental appliance. Also described are compact sensors, e.g., capacitive sensors, that may be included as part of a monitoring electronics unit.

Abstract: Apparatuses for sanitizing and/or sterilizing a dental/orthodontic appliance are described herein. These apparatuses may include an internal chamber in which one or more sanitizing/sterilizing modes, such as UV light (e.g., UVC light), ultrasound, heat, etc. may be applied to an appliance.

Abstract: Pressure-sensor based arrays are integrated into a control device that detects the position, motion, or movement of a one or more body parts of a user to recognize and translate the motion into a unique user-motion profile. The user motion profile may be independently analyzed or recognized as a discrete motion or gesture and used as input or commands for the control device itself or as a signal or set of signals that yields an output signal to a companion device. The pressure sensors can be attached to any body part of a user, such as the user's wrist or ankle. Motion or position, or changes therein, of the user generates an output signal that may be used to control a companion device. The source of the detectable signal is the pressure-based sensor array that yields a pressure data profile that is translated into an output signal to control the companion device.

Abstract: Thin-film pressure sensors are disclosed herein. Such sensors include one or more electrodes in contact with a sensing material. As the sensor deforms the capacitance of the sensor varies and is measurable either between two electrodes of the sensor, or between the one electrode of the sensor and an electrode formed by the surface to which the sensor is applied, such as skin. The sensing material can be an ionic material such as an ionic composite including an ionic liquid.
