BIOPAC’s new Research Ring allows researchers to capture high-quality data from various physiological signals from a small, user-friendly research-grade ring. The Research Ring’s compact, non-intrusive design eliminates the need for straps, bands, and adhesive electrode attachments. The device collects high-quality data such as electrodermal activity (EDA/GSR), pulse (PPG), skin temperature, and when a second point of contact is made, electrocardiogram (ECG), sampling rates can be selected depending on the biosignal. Additional calculated channels can be added using AcqKnowledge, for example: calculate real-time HR/HRV from ECG. For more derived signals, see below. An in-built IMU allows users to measure acceleration and movement. Data is automatically uploaded from the accompanying application to the cloud for analysis and can be synchronized with AcqKnowledge in real time or imported into AcqKnowledge asynchronously from the cloud. Up to 6 rings can be used simultaneously and in synchrony. Data is encrypted and anonymous.

The ring can be used on various finger sizes with the help of different-sized shims to fit adolescents up to adults. The ring itself only weighs 9 grams (or 0.32 oz). The ring can run on a single charge for eight hours and be recharged wirelessly (depending on the selected channels and sampling rate).
