Heatguard: An Ultra-Low-Cost 3D Printed Sensor for Body Temperature Alert and Reporting System

Abstract

The thermochromic device is a low-cost 3D-printed bracelet. It has the function of reading body temperature and warns individuals of the potential risk for heat related illnesses. The product is created from a thermochromic resin that is sensitive to temperature. This product can be customized to fit different age groups such as children and elders. Combined with the smartphone application, the device can provide realtime body temperature monitoring and alert to people who are vulnerable to heatstroke.

Temperature Measurement at Curved Surfaces Using 3D Printed Planar Resistance Temperature Detectors

“…Nonetheless, rigid elements were prone to mechanical damage, while long connections have introduced parasitic resistances, especially noticeable after using elastic encapsulation and putting mechanical stress on the structure [6]. Some other approaches were also discussed, since temperature sensors were made using inkjet printing with conductive ink [16], geopolymers extruded from pressurized cartridges [17], thermochromic materials [18], mixtures of graphene and polydimethylsiloxane (PDMS) [8] and vacuum deposition from nanofilter to PDMS [19]. However, dedicated plotters or non-commercially available mixtures (inks) were required to print these structures.…”

“…However, dedicated plotters or non-commercially available mixtures (inks) were required to print these structures. Recently introduced biomedical applications, such as body temperature reporting systems [18], smart gloves [20], fever alarm armbands [21] and thermal imaging [22] are related with measurements from surfaces with different shapes and sizes. Flexible temperature detectors could be specifically designed for these devices and easily incorporated into their structure.…”
