Abstract: Presented are wearable sensor systems for monitoring user movement, methods for making/using such systems, exoskeletons employing such systems, and wireless-enabled wearable sensor devices for performing biometric measurements. A sensor system for monitoring movement of a user includes a wearable sensor device that is communicatively connectable to a sensor linking node. The sensor linking node wirelessly receives sensor data from the wearable sensor device and wirelessly communicates the received sensor data to a remote computing node. The wearable sensor device includes an expandable device body, such as an elastic compression sleeve or an adjustable strap, that is worn on an appendage of the user. The device body includes a mounting interface, such as mating hook-and-loop fastener pads, that removably mounts thereon a biometric sensor core (BSC) unit.

Abstract: A modular passive-to-active exoskeleton system utilizes motor unit modules, an electromagnetic clutch power transmission system, and biometric control. The passive exoskeleton has a stamina-increasing “chair less chair” function, and optional use of magnetic ball and socket joints and knee torsion springs. To convert the exoskeleton system into an active robotic wearable device, modular attachments allow for motor units to be securely connected to the exoskeletal unit. This exoskeleton contains a knee motor unit that has a transmission system with an electromagnetic clutch that enables a passive mode, active mode, and/or hybrid mode. The motor units are controlled via wireless biometric motion sensors that measure limb joint angle and muscle activity. These motor units also communicate via wireless transmission with a central processing units of the exoskeleton.

Abstract: Disclosed herein are wearable, wireless-enabled biometric sensor systems, methods for manufacturing/operating such biometric sensor systems, and robotic exoskeletons equipped with such biometric sensor systems. A biometric sensor system includes a first biometric subassembly that mounts to an upper-extremity portion of a user's appendage, and a second biometric subassembly that mounts to a lower-extremity portion of the user's appendage. Each biometric subassembly includes a respective biometric sensor that monitors a biometric characteristic of the respective extremity portion of the user appendage and wirelessly outputs a sensor signal indicative thereof. A system central processing unit (CPU), which mounts onto the user, is programmed to receive sensor signals from the biometric sensors, calculate a biometric parameter of the user appendage using biometric characteristics indicated by the received sensor signals, and command a subsystem (e.g.

A passive exoskeleton may have a stamina-increasing “chairless chair” function and optional use of magnetic ball-and-socket joints and knee gas-and-torsion springs. To convert the exoskeleton system into an active wearable robotic device, modular attachments allow for motor units to be securely connected to and disconnected from the exoskeletal frame. An exoskeleton system may employ modular motor units that have a transmission system with an electromagnetic clutch that enables a passive mode, active mode, and/or hybrid mode.
