“…Wearable systems have shown promise in measuring physiological parameters that can be impacted by heat stress such as heart rate, respiratory rate, cardiac function, and core temperature [ 10 , 13 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ], which are valuable predictors of acclimatization to the hot environment. While several of these monitoring systems include multiple technologies built into a shirt or vest, the Slate Safety wearable sensor is attached via an elastic band on the upper arm, and allows for the simultaneous monitoring of estimated core temperature, heart rate, and exertion levels.…”

“…Another concern for a worker is any limitation on the range of motion while wearing any monitoring system. Some currently available systems utilize the wearing of a snugly fitting shirt [ 18 , 19 ], while others utilize a chest strap [ 20 , 21 , 27 ] or wrist band [ 26 ]. The placement of the SS midway between the elbow and the bottom of the lateral deltoid muscle allows for the full range of motion of the elbow and the shoulder while limiting the restriction of the chest or the added potential for heat being trapped close to the body by the extra layer of clothing.…”

“…Wearable devices related to heat stress prevention includes sensors that monitor the sweat production [ 14 , 15 , 16 ], temperature (core, skin, rectal) [ 12 , 17 ], heart rate, variability, recovery rate [ 12 ], and perceived exertion [ 12 ]. Multiple physiological parameters can be collected utilizing smart wearable sensors to measure electrocardiograph (ECG) tracing, blood pressure, pulse pressure, respiratory rate, and pulse oximetry [ 18 , 19 , 20 , 21 , 22 , 23 ] which is recorded in a data acquisition device and transmitted to a monitoring location.…”

Background: With the increase in concern for deaths and illness related to the increase in temperature globally, there is a growing need for real-time monitoring of workers for heat stress indicators. The purpose of this study was to determine the usability of the Slate Safety (SS) wearable physiological monitoring system. Methods: Twenty nurses performed a common task in a moderate or hot environment while wearing the SS device, the Polar 10 monitor, and having taken the e-Celsius ingestible pill. Data from each device was compared for correlation and accuracy. Results: High correlation was determined between the SS wearable device and the Polar 10 system (0.926) and the ingestible pill (0.595). The SS was comfortable to wear and easily monitored multiple participants from a distance. Conclusions: The Slate Safety wearable device demonstrated accuracy in measuring core temperature and heart rate while not restricting the motion of the worker, and provided a remote monitoring platform for physiological parameters.

“…12 shows the calculated R-values from both the ZenPPG channels against the simulated SpO 2 values. A second-degree polynomial was used to derive the following calibration functions from the R-values: Using these calibration curves, the functionality and accuracy of both the ZenPPG channels as pulse oximeters was tested on eight healthy volunteers (aged [21][22][23][24][25][26][27][28][29][30][31][32]. In this brief study, PPG signals were recorded from index and the middle fingers (right hand) of the volunteers using two Masimo reusable sensors (Masimo Inc., California, USA) connected to the ZenPPG system for 2 min.…”

“…One of the many examples of such systems is the Ultra-Low-Power Sensor Evaluation Kit developed by Tobola et al [20] to measure ECG, respiration, motion, body temperature, and PPG. Other examples of such systems include [21]- [23]. The demand for raw PPG signals has also prompted manufacturers to develop integrated analog frontend chips such as the AFE4490 and MAX30100 [24], [25].…”

In this paper, we present the design, development, and validation of a 'modular photoplethysmography (PPG) system called ZenPPG. This portable, dual-channel system has the capability to produce "raw" PPG signals at two different wavelengths using commercial and/or custom-made PPG sensors. The system consists of five modules, each consisting of circuitry required to perform specific tasks, and are all interconnected by a system bus. The ZenPPG system also facilitates the acquisition of other physiological signals on-demand including electrocardiogram (ECG), respiration, and temperature signals. This report describes the technical details and the evaluation of the ZenPPG along with results from a pilot in vivo study on healthy volunteers. The results from the technical evaluations demonstrate the superiority and flexibility of the system. Also, the systems' compatibility with commercial pulse oximetry sensors such as the Masimo reusable sensors was demonstrated, where good quality raw PPG signals were recorded with the signal-to-noise ratio (SNR) of 50.65 dB. The estimated arterial oxygen saturation (SpO 2) values from the system were also in close agreement with commercial pulse oximeters, although the accuracy of the reported SpO 2 value is dependent on the calibration function used. Future work is targeted toward the development of variations of each module, including the laser driver and fiber optic module, onboard data acquisition and signal processing modules. The availability of this system will help researchers from a wide range of disciplines to customize and integrate the ZenPPG system to their research needs and will most definitely enhance research in related fields.
