Abstract: The present disclosure provides touch communication devices that can convey touch information to a human user and/or receive touch information from the human user. As one example, a touch communication device can include a plurality of tactile units. The touch communication device can individually control each of the tactile units to apply a respective pressure to a surface adjacent to such tactile unit. For example, the touch communication device can control the plurality of tactile units to convey a touch communication to a human user that has the touch communication device adjacent to a portion of his body. As another example, the touch communication device is configured to determine a counter-pressure applied to each tactile unit by the surface adjacent to such tactile unit. The touch communication device can generate information descriptive of a touch communication performed by the human user on the touch communication device.

Abstract: The present disclosure provides methods, systems, and devices for non-invasively measuring a level of an analyte in a user using Stimulated Raman Scattering. A device can include a Raman pump source that emits pump light toward a tissue at a pump wavelength and a Stokes source that emits Stokes light toward the tissue at one or more Stokes wavelengths. The device can further include one or more mirrors and lenses. The device can further include a beam controller that controls the one or more mirrors and the one or more lenses to target the pump light emitted by the Raman pump source and the Stokes light emitted by the Stokes source at an optimal target location. The device can further include a photodetector that measures light that emanates from the tissue. The device can further include a processor that estimates the level of the analyte in the user.

Abstract: A wearable device includes at least one attachment member and an electrodermal activity (EDA) sensor comprising an integrated electrode pair physically coupled to the at least one attachment member. The electrodermal activity sensor is configured to provide an EDA signal in response to contact between the integrated electrode pair and a skin surface of a user. The integrated electrode pair includes at least two concentric electrodes radially separated by at least one insulator. Each of the at least two concentric electrodes includes an upper surface configured to contact the skin surface of the user in order to generate the EDA signal.
