A method for detecting a user's intent in an adaptive lower limb device includes providing the adaptive lower limb device. The lower limb device includes a device control unit. The device control unit includes activity controllers and at least one accelerometer. The acceleration features are measured via the at least one accelerometer. The measured acceleration features are determined whether they correspond to a tapping movement initiated by a user with an intent to switch from a first one of the plurality of activity controllers to a second one of the plurality of activity controllers. If the measured accelerating features correspond to the tapping movement, the control unit of the adaptive lower limb device is switched from the first one of the activity controllers to the second one of the activity controllers.

The present disclosure is directed to systems and methods of collecting environmental and/or biometric information and/or data using a chronic monitoring apparatus that includes a wearable expandable support structure to wirelessly receive power via a wireless power transfer antenna disposed in, on, or about the wearable expandable support structure. The chronic monitoring apparatus includes power receiver circuitry, data transmission circuitry, sensor circuitry, and control circuitry. The wearable expandable support structure maintains close contact between at least a portion of the sensor circuitry and the wearer of the chronic monitoring apparatus without requiring the use of adhesives or other bonding agents. The chronic monitoring apparatus communicates the collected environmental and/or biometric information to external data collection circuitry. The components included in the chronic monitoring apparatus are sealed within the wearable expandable support structure providing a rugged, reliable, resilient and waterproof system that is biocompatible, non-irritating and does not require the use of adhesives.

A flexible sheet for neurostimulation has a flexible non-conductive substrate matrix in which electrodes are embedded along a lower surface. Electrically conductive wires extend from the electrodes through the flexible substrate to another exterior surface of the substrate. Methods of making the flexible sheet and making a device using the flexible sheet are also disclosed.

A myoelectric sensor for detecting myoelectric signals which accompany body movement includes: a wearing band that is elastic, expandable, and circular, and that is worn around a limb to surround the limb tightly; myoelectric detection units a plurality of which are disposed in the circumferential direction on the wearing band with intervals therebetween so as to cause each of a plurality of myoelectric detection electrodes to be in close contact with the surface of the limb, and which detect myoelectric signals from corresponding positions on the limb using the myoelectric detection electrodes; and connection cables that electrically connect mutually adjacent myoelectric detection units and thereby transmit the myoelectric signals. The connection cables each include a bent portion, the bent shape of which changes in response to changes in the distance between the mutually adjacent myoelectric detection units.

A wireless patient monitoring device can be fully functional stand-alone patient monitoring device capable of various physiological measurements. The patient monitoring device is small and light enough to be comfortably worn on the patient, such as on the patient's wrist or around the neck. The patient monitoring device can have a monitor instrument removably engaging a disposable base. The base can have outlets for connecting to an acoustic respiration sensor and an oximeter sensor. The patient monitoring device can have pogo pin connectors connecting the monitor instrument and the disposable base so that the monitor instrument can receive sensor data from the sensors connected to the disposable base.

This invention is smart clothing with stretch and/or bend sensors for measuring changes in a person's body configuration. This smart clothing has an elastic nonconductive layer onto which helical converging/diverging conductive pathways are printed using ink which is a mixture of elastic nonconductive material and conductive material. Changes in the transmission of electromagnetic energy through the pathway are analyzed to measure changes in the configuration of the person's body.

A wearable device is disclosed. The wearable device may process a state variable defined based on motion information of a user, determine an interactive mode of the wearable device based on a gain associated with a magnitude of a torque of the wearable device, select a motion type from among motion types of the determined interactive mode based on a gait parameter of the user, determine a control factor for the torque based on the selected motion type, and generate the torque based on the processed state variable, the gain, and the determined control factor.
