Abstract: Methods, systems, and devices for manufacturing of a wearable ring device are described. The method includes coupling a printed circuit board (PCB) to an inner shell, surrounding the inner shell and the PCB with an outer shell, disposing a first molding plate against a first lateral side of the wearable ring device, and filling at least a portion of a cavity of the wearable ring device with a filler material. The method further includes performing a first curing procedure to form a first molded side cover on the first lateral side of the wearable ring device, where the first curing procedure cures a first portion of the filler material. The method further includes performing a second curing procedure to form a second molded side cover on a second lateral side of the wearable ring device, where the second curing procedure cures a second portion of the filler material.

Abstract: Methods, systems, and devices for manufacturing of a wearable ring device are described. Generally, the techniques described herein may support a manufacturing process that reduces manufacturing complexities and deformities. For example, a deformable band may be positioned (e.g., by a manufacturing system) through an inner circumference of an inner housing of a wearable ring device. The manufacturing system may stretch the deformable band to create tension across at least a portion of the inner housing member, the tension including at least axial tension across one or more cutouts in the inner housing member. Accordingly, the manufacturing system may inject a fillable material through an opening in the wearable ring device, such that the fillable material fills a cavity between the inner housing member and an outer housing member of the wearable device and fills the one or more cutouts, contacting the deformable band, without further deforming the deformable band.

Abstract: Methods, systems, and devices for manufacturing of a wearable ring device are described. Generally the techniques described herein may support manufacturing of a wearable ring device with an outer cover capable of rotation. For example, a wearable ring device may include an inner ring assembly, one or more side covers, and an outer cover. The inner ring assembly may be statically coupled, or fixed, to the one or more side covers, while the outer cover may be non-statically, or slidably, coupled to the outer cover, such that the outer cover may rotate around the inner ring assembly while the inner ring assembly remains stationary. In some cases, rotation of the outer cover relative to the inner ring assembly may be harnessed for energy-harvesting purposes, may enable a user to input one or more ring-inputted commands via a sequence of rotations, or both.

Abstract: Methods, systems, and devices for manufacturing a wearable ring device are described. An outer cover may be placed around a ring assembly, including a printed circuit board (PCB) coupled to an inner cover, producing a first slot between the outer cover and the inner cover on a first lateral side of the wearable ring device and a second slot between the between the outer cover and the inner cover on a second lateral side of the wearable ring device. Additionally, a first and second side cover may be inserted into the first and second slots, respectively, where the insertion causes the first and second side covers to mechanically deform. In such cases, the mechanical deformation may cause the first and second side covers to engage one or more locking mechanisms of the inner cover, the outer cover, or both, to secure the inner cover to the outer cover.

Abstract: Systems and devices for a conformable wearable device are described. The wearable device may include a sensor module comprising one or more sensors configured to acquire physiological data from a user. In some cases, the wearable device may include a deformable material coupled with the sensor module and configured to transition between a planar orientation in an unworn state and a non-planar orientation in a worn state and a flexible material that at least partially encases the sensor module and the deformable material. The deformable material may be configured to at least partially conform to a body part of the user to bring the sensor module into contact with the body part of the user when the deformable material is in the worn state. In some cases, the deformable material is further configured to retain the non-planar orientation after being conformed to the body part of the user.

Abstract: A wearable device, such as a wearable ring device, configured to transition between multiple discrete ring sizes is described. For example, the wearable ring device may have an adjustable inner circumference and a rigid outer housing. The inner circumference may be adjusted to transition between multiple discrete ring sizes. For example, a wearable ring device may include a ring housing that exhibits a constant outer circumference, where mechanical components of the ring are configured to adjust at least a portion of an inner circumferential surface to transition the ring between the discrete sizes. The ability of the wearable device to transition between multiple discrete sizes may enable the wearable device to achieve a better fit on a user, thereby improving contact between one or more sensors of the wearable device and the skin of the user, leading to more accurate physiological data readings.

Abstract: A wearable device, such as a wearable ring device, configured to transition between multiple discrete ring sizes is disclosed. The wearable ring device may include a discontinuous ring-shaped housing that extends radially around at least a portion of a circumference of the wearable ring device, where a first end and a second end of the discontinuous ring-shaped housing are separated from one another by a radial distance and configured to move relative to one another. The wearable ring device may further include one or more sensors positioned at least partially within an inner circumferential surface of the discontinuous ring-shaped housing, and one or more mechanical components configured to transition the wearable ring device between the multiple discrete ring sizes.

Abstract: A wearable device, such as a wearable ring device, configured to transition between multiple discrete ring sizes is described. For example, the wearable ring device may include multiple rings coupled to one another (e.g., adjacent, parallel, or concentric rings), where a user may manipulate or adjust the rings relative to one another to transition between multiple discrete ring sizes. In some cases, the multiple rings may be oval or elliptical-shaped, where rotating the rings relative to one another may change the size of the ring. In some other cases, the multiple rings may be threaded such that they may be screwed into and out of one another. In some other cases, the wearable ring device may include a long housing that may coil into itself to form multiple concentric loops, where coiling or uncoiling the concentric loops adjusts the ring size.

Abstract: Systems and devices for a wearable ring device are described. The wearable ring device may include a housing comprising one or more sensors configured to acquire physiological data from a user and a deformable material extending along one or more portions of an inner circumferential surface of the housing. The deformable material may be configured to exert pressure on a digit of the user by conforming to an outer circumferential surface of the digit to form an interference fit with the digit of the user when the wearable ring device is worn by the user. In some cases, the deformable material may be arranged to enhance a signal quality of measurements by the one or more sensors through an application of pressure on the digit of the user within an area of the digit adjacent to the one or more sensors.

Abstract: A wearable device is described. The wearable device may be constructed of one or more flexible materials, and may be referred to as a flexible wearable device. The flexible wearable device may include a flexible housing that is made of a material that is elastically deformable, where the flexible housing at least partially surrounds components of the flexible wearable device. The flexible housing may include apertures disposed within the surface of the flexible housing to enable light to be transmitted and received through the flexible housing. The flexible wearable device may also include a printed circuit board (PCB) disposed within the flexible housing (e.g., within a cavity formed by the flexible housing). The PCB may include sensors configured to acquire physiological data from a user by transmitting light and receiving light through the apertures. The PCB may be constructed of flexible regions that are elastically deformable.
