1.2. Typical Unfiltered Sensor Output Figure 2 shows a typical unfiltered Electrooculography sensor output acquired while blinking. The raw digital sensor values received from the biosignalsplux device ranged between 0 and 2 -1 (n=sampling resolution) were converted into the original unit of measurement of this sensor (mV) using the transfer function found in section Transfer Function (Conversion Formula). -

> Biomedical device prototyping > Biomedical research 1.6. Transfer Function (Conversion Formula) The analog sensor signals acquired with biosignalsplux devices are converted into digital values ranged between 0 and 2 -1 (n=sampling resolution, usually 8-bit or 16-bit) and streamed in the raw digital format. -

Page 7: Application Notes
User Manual 2. Application Notes The biosignalsplux EOG is designed to be used in, essentially, two configurations that may be combined. Given its bipolar configuration, the measured signals correspond to the differential between two electrodes given the reference electrode. The relative positioning of the two electrodes (positive and negative) allows to infer about the eye movements, specifically, vertical or horizontal movements. -

Electrooculography (EOG) User Manual 2.2. Vertical Electrode Setup Figure 5 - Placement of the electrodes to measure vertical eye movements. For example, if the subject looks up, this will result in a positive peak in the signal, if the subject looks down, this will lead to a negative peak. -

3.1. Connecting the sensor to biosignalsplux Systems 3.1.1. biosignalsplux 4-Channel Hubs The biosignalsplux EOG sensor is compatible with all 8 analog input channels of the 4-channel biosignalsplux hub, but incompatible with the reference/ground port. Connect the sensor to an analog input to use it with this device. -

User Manual 3.1.3. biosignalsplux Solo & Single-Channel openBAN Devices The biosignalsplux EOG sensor is compatible with the analog input channel of the biosignalsplux Solo (openBAN) device. Connect the sensor to the analog input channel to use it with this device. - Page 11 Figure 11: Enabling the device for acquisition. Click on the biosignalsplux logo to access the available settings. Select the channel your sensor is connected to and select the RAW from the dropdown menu highlighted in the next screenshot, as the EOG option is not yet available (after the acquisition, the acquired data should be converted to the physical units using the above presented transfer function).

Page 13: Safety & Maintenance
The user should always keep the device and its accessories dry. The user must turn off the biosignalsplux device and contact Technical Support if the system or accessories reach uncomfortable temperatures. The user should not use the biosignalsplux device in noisy environments (environments with microwaves and other similar equipment). -
Page 14: Transportation And Storage
Please follow these recommendations to ensure safe transportation and storage of your biosignalsplux equipment and sensors to prevent any damaging of your system. The biosignalsplux equipment and sensors should be stored in the original box in a dry place when those are not being used. -
