THE RESEARCH RING GIVES RESEARCHERS NEW POSSIBILITIES!

The ring allows researchers to gather physiological and other data “in the wild,” in everyday settings with their study participants. This has generally not been feasible because data acquisition hardware and software has historically required large, computer-connected signal acquisition systems, and lab-friendly (but not user-friendly) systems, cables, sensors and software. While more portable systems have evolved, the problem with many of them is that they do not capture high-quality data that researchers can use for peer-reviewed studies.

• EDA: Gold-plated dry electrodes—no electrolyte required, Sampling rate up to 400 Hz
• PPG: Dual green LEDs + frequency tuned photosensors, Module output and peak picking in the app, Sampling rate up to 400 Hz
• ECG: Gold-plated dry electrodes, Sampling rate up to 800 Hz
• Temperature

If researchers want to study a user’s psychophysiological and other contextual data, they can give the Research Ring to a study participant along with a companion mobile application. This “mobile first” approach is also cloud-friendly. The data is collected on the iPhone and can be immediately stored on the cloud when a data collection session ends. The ring comes with the phone app and a year of Senstream Cloud.

*BIOPAC INTEGRATION  In addition to being a stand-alone research tool, the Research Ring can also be used with AcqKnowledge Research Ring Software (ACK100W-RNG) for in-lab applications or to import data acquired from the phone app to the cloud into AcqKnowledge. AcqKnowledge Research Ring Software can interface up to nine rings per computer and installation also provides a single license for Basic Scripting and Workflow drag-and-drop automation.

Adapters and Windows

The recommended BT adapters use Intel drivers for wireless chips in the Wi-Fi 6E family: AX210, AX211 or AX411, or from the Wi-Fi 6 family: AX:201.

Current release software allows up to nine Research Rings to communicate with a single computer only if the Intel drivers for these recommended chips are detected.

Other adapters with external antennas can provide extended  range but only allow reliable communication for up to two Research Rings; if drivers for that type of adapter are detected, the maximum allowed concurrent connections is restricted to two rings per computer.

If the adapter is not recognized, the maximum allowed concurrent connections is restricted to three rings per computer.
