“…At the time of this study there was no previous research conducted comparing smartphone ambient temperature senors with other types of ambient temperature sensors. However, theoretically, within the range of temperatures encountered in this study, both silicon band-gap and thermistor sensors have similarly high sensitivity (Burlet et al, 2015;Kester et al, 1999;National Instruments, 2010). Moreover, the Sensirion SHTC1 and Met One 064-2 are both moderately accurate (± 0.3°C and ± 0.1°C respectively) (Met One Instruments, 2010;Sensirion, 2013).…”

“…Thermocouple sensors have the largest range of any electronic temperature sensor. They are often selected because of their ability to function under extreme temperatures, however, due to the physical properties of the metals used, they are subject to a drift in readings over time (Ferreira, 2012;Kester, Bryant, & Jung, 1999). This means that regular calibration is crucial to ensure accurate readings.…”

“…The second type of sensor is the RTD. It is more linear than a thermocouple sensor which gives it much more accurate readings and its temperature range is still quite large (Kester et al, 1999). However, an important limiting factor for its usage is its low sensitivity (Storr, 2015).…”

“…Finally, semiconductor sensors are the best suited for use in ambient temperature monitoring. They are generally low cost, have good linearity and as a consequence good accuracy, as well as a range closer to what would be encountered in the environment (Ferreira, 2012;Kester et al, 1999). They also have the added benefit of requiring very little calibration during its lifespan; due to the stable crystalline structure of the silicon, very little drift in accuracy over time can be observed (Ferreira, 2012).…”

Background: Heat-related illness during extreme weather events is a leading cause of death and morbidity among vulnerable populations. Heat health alert systems are crucial in preventing serious impacts due to extreme heat, however its efficacy is limited by available atmospheric temperature data. A study was conducted to determine the accuracy of a silicon band-gap sensor integrated into certain models of smartphones when compared to a well-documented thermistor themperature sensor. Methods: Ambient temperature readings were taken at a location chosen within Burnaby, BC, using both a Met One sensor and a Sensirion sensor integrated into a smartphone. The data was then analyzed using a dependent T-test for paired samples to determine whether there was a significant difference between the grouped readings. Results: According to the results of the dependent T-test with data adjusted to a calibration curve, it was determined that there was no difference between the readings taken by the Met One and the Sensirion sensors, t(30)= -0.68, p=0.5 (95% CI, -0.04 to 0.02). Conclusions: Although further research is needed, the results of this study suggest that temperature sensors found in smartphones may be a smaller, lower-cost, and more accessible alternative to some of the higher-end models currently used to measure ambient temperature for the purposes of public health planning and policy-making.

“…For instance, the relationship between the output voltage and the temperature measurements is not linear, and each type of sensor exhibits its distinctive non-linearity. For this reason, analog temperature sensors often require high-resolution ADCs to achieve the desired accuracy [55]. Also, thermocouples require an additional correction to the acquired measurement called Cold-junction compensation (CJC).…”

Temperature sensing and control systems are widely used in the closed-loop control of critical processes such as maintaining the thermal stability of patients, or in alarm systems for detecting temperature-related hazards. However, the security of these systems has yet to be completely explored, leaving potential attack surfaces that can be exploited to take control over critical systems.In this paper we investigate the reliability of temperature-based control systems from a security and safety perspective. We show how unexpected consequences and safety risks can be induced by physical-level attacks on analog temperature sensing components. For instance, we demonstrate that an adversary could remotely manipulate the temperature sensor measurements of an infant incubator to cause potential safety issues, without tampering with the victim system or triggering automatic temperature alarms. This attack exploits the unintended rectification effect that can be induced in operational and instrumentation amplifiers to control the sensor output, tricking the internal control loop of the victim system to heat up or cool down. Furthermore, we show how the exploit of this hardware-level vulnerability could affect different classes of analog sensors that share similar signal conditioning processes.Our experimental results indicate that conventional defenses commonly deployed in these systems are not sufficient to mitigate the threat, so we propose a prototype design of a low-cost anomaly detector for critical applications to ensure the integrity of temperature sensor signals.

For surgeries involving vessel anastomosis, it is critical to ensure fluent blood flow and to monitor the occurrence of vascular complications. However, the current clinical methods are ineffective in achieving direct, continuous, and accurate monitoring. At present, implantable sensors are widely used and explored in various biomedical applications, including cardiovascular disease, neurological disorders, cancer treatment, and health monitoring. They can be easily placed during surgical procedures and offer irreplaceable advantages including directness, continuity, and higher accuracy of monitoring. Based on this, the types of implantable sensors for vascular monitoring are reviewed, and some preclinical research advances which are expected to provide promising methods for post‐surgical vascular complications are discussed. In the end, the future perspectives of the research of implantable sensors for post‐surgical monitoring are put forward. It is believed that implantable sensors hold great promise in clinical translation, providing physicians with more accurate, continuous, and real‐time monitoring results, helping to improve surgical success and patient outcomes.
