A tissue splayer (76) is described which includes an index finger portion (4) and a middle finger portion (5). The tissue splayer also includes a first pivot joint (80) coupling the index finger portion (4) to the middle finger portion (5) to permit the middle finger portion (5) to rotate relative to the index finger portion (4) about a first pivot axis (81). The tissue splayer (76) also includes a first splay mechanism (88) configured to permit rotation of the middle finger portion (5) away from the index finger portion (4) about the first pivot axis, and to resist rotation of the middle finger portion (5) towards the index finger portion (4) about the first pivot axis (81).

A device and method for detecting control-point activation conditions corresponding to a portion of a glove body coming in contact with or being within a threshold distance from at least one of another portion of the glove body or a control surface separate from the glove body. The glove may include a conductive path attached to the glove body and an expanded conductive area conductively coupled to the conductive path and attached to the glove body. The expanded conductive area may be wider than individual portions of the conductive path.

In one embodiment, a hydration sensor or sensing element is configured to measure the hydration level of a user. The sensing element can include a water-permeable material positioned in between two water-impermeable material. The sensing element can be coupled to a bottle of fluid, or a carrier with a timer. The sensing element can be incorporated into a handheld device. The sensing element can be a disposable element, an element applicable for more than one-time use, or a re-usable element. The sensing element or sensor can be calibrated for a specific user or a group of users. One or more additional sensors that do not measure hydration level of the user can be coupled to a hydration sensing element to determine the amount of fluid consumption for the user in different conditions.

A method (200) for predicting a wellness metric (208, 314, 612) is presented. The method (200) includes maintaining (202) a model which receives as input a set of parameters and provides as output a wellness metric (208, 314, 612). Furthermore, the method (200) includes receiving (204) a set of non-invasive biological parameters (106, 404, 602) of a user (102). In 5 addition, the method (200) includes providing (206) the set of non-invasive biological parameters (106, 404, 602) as the set of parameters to the model to cause the model to generate a wellness metric (208, 314, 612) for the user (102).

A sensing device including a sensor, a triggering mechanism is provided. The sensing device is attachable to a covering positioned in contact with a body such that the triggering mechanism extends between first and second segments of the body. Movement of at least one of the first and second segments activates the triggering mechanism to provide an input to the sensor, actuating the sensor to generate an output defining at least one measurement of the movement. The measurement may be one or more of rotation, translation, velocity, acceleration, and joint angle. An intermediate mechanism may be interposed between the triggering mechanism and the sensor. The sensing device may include a means to process or record measurements corresponding to movement. A system and method of measuring the movement is also provided.

The present disclosure describes systems, devices, and methods for determining stability of a joint of a living subject. In one aspect, a force-measuring device for determining stability of a joint of a living subject is provided. In some examples, the force-measuring device includes a mitt frame configured to receive a hand of a user therein, one or more first force sensors, and one or more second force sensors. The mitt frame may include a palm portion configured to receive a palm of the user therein, and a finger portion configured to receive fingers of the user therein. The one or more first force sensors may be coupled to the palm portion and disposed on an exterior surface of the palm portion. The one or more second force sensors may be coupled to the finger portion and disposed on an exterior surface of the finger portion.

A wearable device for detecting physiological parameters of a patient is provided. The device includes a flexible body for covering at least a portion a wearer's hand, the flexible body having an interior side and an exterior side. The device may also include a first sensor positioned on the body for measuring the pH of the patient on an exterior side of the flexible body. The device may further include a second sensor positioned on the body for measuring the bicarbonate level of the patient on an exterior side of the flexible body.

A functional electrical stimulation (FES) device includes electrodes arranged to apply functional electrical stimulation to a body part of the user. FES stimulation is performed by: receiving values of a set of user metrics for the user; receiving a target position of the body part represented as values for a set of body part position measurements; determining a user-specific energization pattern for producing the target position based on the received target position and the received values of the set of user metrics for the user; and energizing the electrodes of the FES device in accordance with the determined user-specific energization pattern. The determination may utilize an FES calibration database with records having fields containing: values of the set of user metrics for reference users; energization patterns; and values of the set of body part position metrics for positions assumed by the body part in response to applying the energization patterns.

Various systems are disclosed herein for detecting, monitoring, evaluating, and characterizing pain. They systems include a number of connected components, such as a provider device, a body-mapping system, a patient device, a user device, a referred pain device and/or a rectal probe device. Accordingly, the systems allow providers to track location-specific pain intensity for any number of patients over time in order to generate reports and determine treatment recommendations for such patients.

An Internet of Thing (IoT) device includes a camera coupled to a processor; and a wireless transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.
