“…The results obtained during the lab module indicate that these small concentrations of interferents did not significantly affect the glucose quantification. The selection of interferent concentrations took into consideration their physiological relevance in the context of wearable sensors, as the concentrations of dopamine, serotonin, and glutamate in sweat are typically low. − Therefore, using interferents with lower concentrations does not necessarily indicate that the sensor is more sensitive to them than to glucose. Given the time limitations of the demonstration, a selectivity study was performed as described to provide students with an understanding of the process.…”

This report presents an interdisciplinary approach used in undergraduate laboratory classes to bridge the gap between scientific advances, engineering efforts, and practical applications in daily life. The field of biointegrated electronics is highlighted as an excellent opportunity for building interdisciplinary learning models, leveraging expertise from multiple research areas. Wearable glucose sensors are presented as a promising application that requires knowledge of chemistry, materials science, electrical engineering, and mechanical engineering. The laboratory experiment module provides students with hands-on experience in designing, fabricating, integrating, and testing wearable glucose sensors. This lab class serves as an example of how interdisciplinary research can be integrated into undergraduate education and offers values, skills, and experiences for future careers.

“…As one important access for flexible devices, screen printing stands out as a result of its fast pattern production, low cost, , and scalability, , making it a key focus in areas such as transparent conductive films, − photothermal conversion devices, − and biosensing sensors. − The good homogeneity and viscosity are favorable for functional inks of screen printing. However, the large volume of carbon fibers often leads to poor dispersion in solvents, which is undesirable for printing ink applications.…”

With the fast development of the smart lifestyle in recent years, simple and flexible body condition monitoring has become more and more important. However, currently, commercially available motion-sensing devices always lack flexibility or at a high cost. This article has fully explored the merits of a commercial and easily available material of carbon fiber powder (CFP) and prepared CFP-based screen printing inks. This conductive ink can be directly and quickly printed onto a variety of different flexible common substrates, such as paper, cotton fabrics, etc., to prepare flexible sensors. At the same time, as a result of the good photothermal performance and conductivity of CFP, the printed flexible sensors have fast and stable performance on thermal and human motion detection. The use of CFP as the smart element to construct a wearable device will offer a choice for the intelligent industry.
