Once relegated to tightly controlled lab environments where electrode-laden participants were observed at close quarters, researchers are now able to extend the lab into the everyday environment over nearly limitless distances. Top quality physiological data can be acquired from untethered subjects performing tasks ranging from sleeping comfortably in their own beds to engaging in high-impact sports. How and when did this deep dive into unfettered physiology become possible? We offer a brief examination of the solutions currently offered as the 2020s emerge.
Lightweight, comfortable, and some might even say fashionable, the BioNomadix BioShirt uses a respiration sensor and fabric electrodes to wirelessly record respiration and ECG from ambulatory subjects performing unfettered tasks in short or long-term studies, in the lab, or in the real world. The shirt connects to a BioNomadix wireless Respiration & ECG Transmitter (BN-RSPEC) secured in a small pocket on the front of the BioShirt—no electrodes, gels, or wires need apply. Wireless data can be transmitted to a BioNomadix Smart Center, Logger or matched Receiver+MP160/MP150 System. BioShirts provide a high level of comfort and are ideal for long-term physiological monitoring. The ECG and respiratory signal are obtained by means of sensors made of yarns that are fully integrated into the shirt’s textile structure. Sensors are made of fibers directly woven during the production process, and connections between sensors are obtained using conductive fibers for a totally unobtrusive, highly comfortable sensorized garment. The base yarn is composed of anallergic and antibacterial materials to guarantee safe and prolonged use. Machine washable with mild detergent—do NOT use fabric softener.
The BioNomadix Smart Center is a small-form USB-powered data acquisition unit that can record data from up to three wireless BioNomadix transmitters at a time. The transmitters are automatically detected and paired using a guided setup wizard. Smart Center is compatible with 14 different BioNomadix Transmitter types encompassing all major body signals. AcqKnowledge data acquisition and data analysis software also supports monitoring transmitter battery levels, automatic configuration of derived signals and guided analysis based on the type of recorded signals. Adhesive Velcro disks are included for mounting on various surfaces. Smart Center offers a compact and sophisticated physiology platform that sets up in minutes. Simply plug the Smart Center into the computer, set up the transmitters and subject, then start recording high quality data with AcqKnowledge software.
Offering the industry’s only system that delivers a comprehensive, 24-hour data logging solution in an easy-to-use, easy-to-wear package, the BioNomadix Logger truly delivers “physiology anywhere.” The BioNomadix Logger is the perfect tool for applications that demand greater degrees of subject freedom and complex experimental design. BioNomadix Loggers wirelessly record physiological data as subjects freely and naturally live their lives.
BioHarness with AcqKnowledge software is a lightweight portable biological data logger and telemetry system that monitors, analyzes, and records a variety of physiological parameters including ECG, respiration, posture, and acceleration. BioHarness applications include physiology, psychology, psychophysiology, exercise physiology, ergonomics, human factors, and more. The BioHarness operates in Bluetooth transmitting mode for live viewing of data or data logging mode. In the data logging mode, BioHarness acquires and saves the data for later download to AcqKnowledge software using the included USB docking and charging cradle.
The ETVision (ETV) wearable unit resembles a pair of eyeglasses that can be worn by itself or over the participant’s prescription eyeglasses. The glasses incorporate miniature “eye cameras” for viewing each eye and a “scene camera” that views what the participant is looking at. A built-in microphone is included, and an optional visor can be mounted to the front of the headgear. Recording video and audio data to an SD card for later data processing allows the participant to be completely untethered during data recording. This is useful while engaging in long term activities away from the lab such as walking, bicycling, or driving.
