Flexible EMG Strap Assembly for Stable Skin Contact Sensing

The patent applies this principle by replacing traditional rigid EMG sensor housings with flexible materials. The sensor assembly is enclosed in a flexible shell that can conform to skin contours, maintaining consistent contact during movement while preserving the internal circuit structure. This resolves the contradiction by enabling reliable readings through improved contact without significantly increasing manufacturing complexity.

The patent changes the physical state and mechanical properties of the sensor housing from rigid to flexible. By modifying the material parameters (flexibility, elasticity) of the sensor enclosure, the device adapts to skin surface variations while maintaining stable electrode-skin contact, thereby improving reading reliability without complex structural modifications.

The flexible strap body with integrated circuit board creates a soft, conformable wearable device that eliminates the discomfort of rigid sensors against the skin. The flexible construction allows the device to move with the body during long-term monitoring, significantly improving wearability and user comfort.

The strap incorporates flexible, movable components that adapt to body movements rather than maintaining a fixed rigid structure. The flexible circuit board and soft housing allow dynamic adjustment to skin contours and movement patterns, enhancing comfort during extended use without requiring complex active adjustment mechanisms.

The flexible circuit board is housed within a flexible strap body that naturally conforms to body contours. The flexibility of both the housing and circuit board allows them to adapt to curved surfaces without requiring precision manufacturing to achieve perfect alignment, as the materials themselves provide the necessary geometric adaptation.

The device uses composite construction with flexible housing materials and flexible circuit board materials that work together to achieve contour conformity. The combination of these compliant materials allows the device to adapt to body shapes through material properties rather than precision-engineered geometric features, reducing manufacturing precision requirements.
