Minimally Invasive Microneedle Sensors Developments in Wearable Healthcare Devices

Abstract

In this decade, the market for minimally invasive wearable devices has been booming due to the surge in smart adaptation and commercialization. Smart adaptation has enabled many clinics to provide patients with wearable sensors and devices that can continuously monitor their health and well-being. Advances in material science and miniaturization technologies have increasingly improved the feasibility of wearable electronic devices. The progressive trends in these domains have subsequently aided in the advent of wearable technology, which has significant implications in advancing the existing standards of telemedicine. The wearable devices have immense potential in real-time healthcare monitoring and may also aid in discerning the progress or cure of a disease. Also, the Covid-19 pandemic, which has resulted in stringent social distancing norms, might result in an increased reluctance to in-person visits to clinics/hospitals for regular medical check-ups. Thus, it lays the road for the field of real-time healthcare monitoring to garner a more cardinal status in near future. Since sensors are a pivotal component in wearable devices, it becomes quintessential to discern the challenges and opportunities associated with fabricating such nano-sensors. Hence, this chapter discusses the recent developments in nano-sensors used in real-time healthcare monitoring devices.
