Provided is a biological information detection device capable of restraining noise from being mixed with a signal relating to biological information. A biological information detection device includes an electrode pad that is able to detect a signal (bioelectric signal) relating to biological information of a subject (for example, a fetus in a mother's body), a connector that is connectable to the electrode pad, and a cable that is connected to the connector and is able to transmit the signal. The electrode pad and the connector are provided with fixing members and that are attachable to and detachable from each other, respectively.

Embodiments of the disclosure provide systems and methods for wearable dry electrodes for collecting biometric information. According to one embodiment, a dry electrode bio-sensor can comprise one or more conductive pads comprising electrodes of the dry electrode bio-sensor and one or more connectivity traces coupled with each of the one or more conductive pads. The connectivity traces can provide electrical connections for one or more of power to the one or more conductive pads or signals comprising biometric information from the one or more conductive pads. A backing can be coupled with and can retain the one or more conductive pads and the one or more connectivity traces. The dry electrode bio-sensor can comprise an electrocardiography (ECG) sensor, a respiration sensor, a PhotoPlethysmoGram (PPG) sensor, a temperature sensor, an electromyography (EMG) sensor, or another biometric sensor.

In the present invention, a system and associated method is provided for monitoring fetal vital parameters. The system includes a base unit, a monitoring hub including a digital signal processor/controller and operably connected to the base unit by a single channel digital signal protocol cable, e.g., a USB cable, and a number of fetal monitoring sensors operably connected to the monitoring hub. The controller processes the signals from the sensors into a single USB protocol which can be sent along a single cable to the base unit. The USB cable allows power to be supplied to the hub in order to charge a battery used to operate the hub and the sensors connected to the hub when disconnected from the base unit to allow the patient using the hub to move freely about the base unit, with all sensor signals from the hub being wirelessly transmitted to the base unit.
