Provided are structurally-reconfigurable, optical metasurfaces constructed by, for example, integrating a plasmonic lattice array in the gap between a pair of microbodies that serve to locally amplify the strain created on an elastomeric substrate by an external mechanical stimulus. The spatial arrangement and therefore the optical response of the plasmonic lattice array is reversible.

The present invention relates to a system for monitoring a physical movements of a user, the system comprising: a detection unit configured for receiving a signal obtained by a sensor device representative of a sensed bodily activity, calculating a load index value and communicate, e.g. to the user wearing the sensor device, the value of the load index value. The invention also relates to a method for monitoring and evaluating physical movement of a user and providing feedback to the user.

A surgical device includes an adapter assembly including a tubular housing having a proximal end portion configured to couple to a handle assembly, and a load sensing assembly disposed with the tubular housing. The load sensing assembly is configured to measure a load exerted on the tubular housing and includes: a sensor body including a pocket defined therein; a load sensor circuit disposed within the pocket and coupled to the sensor body; a signal processing circuit disposed within the pocket and electrically coupled to the load sensor circuit; a cover defining a cavity and disposed over the pocket and enclosing the load sensor circuit and the signal processing circuit therein, the cover being coupled to the sensor body thereby forming a first hermetic seal therebetween; and a thermal management material disposed within the cavity and in contact with the load sensor circuit and the signal processing circuit.

The present invention discloses a surgical traction system with a hand gripped tension adjustment device that slidably mounts onto a boom structure. When activated the tension adjustment device moves down the boom structure and incrementally adjusts the tension in a traction rope. The boom structure attaches to a bracket assembly that mounts onto the short end of a surgical table.

A wearable device may include a sensor. The sensor may include a flexible fabric, a conjugated polymer coating deposited on the fabric via vapor-phase oxidative chemical vapor deposition (oCVD), and a plurality of electrodes in coupled to the conjugated polymer coating. The wearable device may further include a processor communicatively coupled to the electrodes. The processor may measure an electrical property across the electrodes, determine a physiological event based on the measured electrical property, and output measurement information corresponding the physiological event.

An intraoral moisture measuring device includes: a swing member that swings with respect to a main body about a predetermined swing center; a moisture amount detection unit provided at a tip of the swing member, for detecting a moisture amount by being directly or indirectly abutted against a measurement site in a mouth; and a biasing member for biasing the swing member in one of swing directions. Consequently, the intraoral moisture measuring device is capable of measuring intraoral moisture in a simple and highly-accurate manner.

A stretch-measurement probe includes an elongate outer sleeve, expansion feature associated with a distal portion of the outer sleeve, and an elongate inner rod disposed at least partially within the outer sleeve. The expansion feature is configured to allow a longitudinal distance between a proximal end of the outer sleeve and the distal end of the outer sleeve to be varied.

In one embodiment, a device for in vivo tissue evaluation includes an elongated manipulator including an elongated proximal tube and an articulable distal portion, and a sensor provided at a distal end of the articulable distal portion, the sensor including a sensor head configured to be pressed against tissue and measure a reaction force of the tissue.
