Systems, methods, and devices include a neurological function assessment system involving a first assessment tool (e.g., hammer) with one or more first sensors. The system includes a second assessment tool being a wearable device operable to wrap around a body part of a subject. One or more second sensors are disposed on the wearable device operable to sense a target area at the body part. The system collects first sensor data, from the first assessment tool, corresponding to an assessment event at the first assessment tool; and collects second sensor data, from the second assessment tool, corresponding to the assessment event. Additionally, the system presents, at a display, an indication of an objective neurological assessment parameter value calculated based on the first sensor data and the second sensor data. An objective neurological assessment parameter value can be calculated based on the first sensor data and/or the second sensor data.

Systems, methods, and devices include a frustrated total internal refraction (FTIR) based scanning device. The FTIR based scanning device has a transparent media and one or more electromagnetic wave emitters operable to provide a scanning light into the transparent media during a sample scanning procedure. One or more electromagnetic wave sensors, cameras, and/or microscopes are directed at a detection surface of the transparent media. These detection component(s) receive scattered light passing from the sample contact surface through the detection surface. The device uses the scattered light to represent a surface topology or a material composition of a sample contacting the sample contact surface during the sample scanning procedure. Additionally, the one or more electromagnetic wave emitters can include a plurality of LEDs or electromagnetic wave emitters corresponding to a plurality of different wavelengths which are used to generate an image of a 3D topology from the scattered light.

Systems, methods, and devices include one or more acoustics-controlling device(s). The acoustics-controlling device(s) comprise implants, fixations, patches, and/or coatings formed of a metamaterial to create a particular behavior when exposed to sound waves. An acoustic metamaterial manipulates the acoustic waves that reach it. The metamaterial has a non-uniform material distribution, a non-uniform geometry, and/or a non-uniform material property, such as a non-uniform density, a non-uniform modulus of elasticity, a non-uniform bulk modulus, combinations thereof, and so forth. The system(s) include acoustic controlling patches and implants which control a path of an acoustic signal generated by one or more speakers. An acoustic-controlling patch can include an acoustic Fresnel lens or an acoustic Luneburg lens formed onto a substrate. Furthermore, manipulating the acoustic signal includes focusing the acoustic signal, forming an acoustic vortex from the acoustic signal, steering the acoustic signal, guiding the acoustic signal, or bending the acoustic signal.

Systems, methods, and devices include a wearable device to stimulate or analyze biological systems or implantable objects. The system includes a substrate material and a plurality of acoustic actuators disposed on the substrate material. The plurality of acoustic actuators are operable to generate an acoustic stimulation signal directed to a target area. The system also includes a plurality of acoustic sensors disposed on the substrate material and operable to receive an acoustic response signal from the target area. Furthermore, a plurality of electrical electrodes disposed on the substrate material are operable to generate an electrical stimulation signal directed to the target area and receive an electrical response from the target area. The substrate material forms a sleeve or a cuff, a glove, a head cap, a back harness, a waist binder, a torso binder, and/or an abdominal binder.

A system includes a first device having a handle, a head coupled to the handle, a bumper supported by a first end of the head and adapted to be used to strike a patient tendon, a force sensor coupled to the bumper and adapted to generate force data in response to force encountered by the bumper and to generate force data, a first accelerometer coupled to generate head acceleration data in response to movement of the head, and first circuitry to capture the force data and acceleration data. The system may further include second device having a housing adapted to be coupled to the patient limb, a second accelerometer supported by the housing to generate limb acceleration data, and second circuitry to capture the acceleration data.
