Abstract: Systems and methods for a wearable sensor system including a compressible material, a two-dimensional array of distance sensors, a support structure, and a controller. The compressible material is positionable relative to a tissue surface and the two-dimensional array of distance sensors is configured relative to the compressible material to detect compressive deformations of the compressible material. The support structure is configured to hold the compressible material in place relative to the tissue surface such that muscle movements at the tissue surface cause the compressive deformations of the compressible material and is also configured to restrict movement of the two-dimensional array during the muscle movements.

Abstract: A guidewire securement device includes a base and an upper section. The upper section includes an aperture and a slit extending from the aperture a distance toward the base. A split in the upper section allows access to the aperture. At least the upper section is formed from a deformable material that allows for selective widening of the split for gaining greater access to the aperture and slit. A guidewire may be passed through the split and into the aperture to be secured by the device. Further passing the guidewire into the slit allows the device to grip the guidewire and limit longitudinal translation.
