Systems, devices, and methods for electrophysiological recording from the eye are disclosed herein. An electroretinography device can detect a biopotential signal from an eye of a subject and transmit the same to a processor. Embodiments of the present technology include one or more features directed to improving the use and operability of an electroretinography device. For example, the device can include features for (i) inhibiting multiple devices from adhering or sticking to one another or a different object and (ii) providing tactile feedback to users to help distinguish one side of the device from the other.

A device for skin-contact biological measurement includes one or more electrodes to enable signal transmission through a skin contact and a control mechanism coupled to the one or more electrodes to adjust an electrode-to-skin impedance (ESI). The control mechanism is configured to implement the ESI adjustment using a thermal actuator.

The present invention relates to a body-attached electromyogram sensor that detects signals from a muscle and provides the degree of contraction and relaxation of the muscle. More specifically, the present invention relates to a body-attached electromyogram sensor that is formed very thin so that the electromyogram sensor may be attached more naturally inside a socket physically connecting a robot leg of an amputee, and thus is more comfortable to wear. In addition, the body-attached electromyogram sensor is made of a material that is elastic and thus naturally expands and contracts according to the movement of the muscle, and is breathable and thus may effectively discharge secretions such as sweat. Accordingly, the body-attached electromyogram sensor may be worn repeatedly and attached for long periods of time.

A pessary system for providing pelvic floor support for USL and other ligaments. The pessary has an elongated probe with independently inflatable balloons each located substantially the same distance from the insertion end of the probe and which inflate into separate radial sectors. The probe can be inserted into a vaginal cavity and the balloons inflated provide mechanical support to the USLs. Independent inflation of each balloon allows the mechanical USL support provided to be varied on left and right sides to compensate for differences in the degree of degradation and positioning of the USL ligaments on either side.
