Current view and prospect: Implantable pressure sensors for health and surgical care

Abstract

Health monitoring and screening have entered a period of rapid change. Popular terminology refers to this as mobile health (mHealth), which is a direct evolution of eHealth, but is really data‐driven technology—sensors oriented for health care. Medical decision support through this technology is the first step towards more personalized and preventative medicine. Pressure is one of the easiest and most interesting physiological parameters to assess whether organs or biological systems are healthy in the body. Pressure recordings are commonly used for clinical diagnosis and monitoring; however, the invasiveness of current technologies and associated risks of infection limit the windows in which data can be gathered. This review discusses the importance of pressure in the body and how monitoring is performed. It also describes newer and commercially available sensors, as well as how they can be improved to become minimally invasive, fully wireless pressure sensors for continuous monitoring.

Perspectives on smart stents with sensors: From conventional permanent to novel bioabsorbable smart stent technologies

“…Top of microposts will carry the cell body with membrane, while filopodia structures can extend through the gaps to the detection area with nanoplasmonic sensors. Reprinted from Zhu et al 2020 (Han, Kundu, Nag, & Xu, 2019;Honjol et al, 2020). Chow, Ouyang, Beier, Chappell, and Irazoqui (2009) developed an active sensing stent to analyse the pulmonary arterial pressures both in vivo and by simulations for calculating tissue-induced power loss.…”

“…The early signs of in‐stent restenosis can be detected with the aid of a pressure sensor by proper monitoring of these parameters. Various types of pressure sensors and their mechanisms for distinctive biomedical applications are recently reviewed (Han, Kundu, Nag, & Xu, 2019; Honjol et al, 2020). Chow, Ouyang, Beier, Chappell, and Irazoqui (2009) developed an active sensing stent to analyse the pulmonary arterial pressures both in vivo and by simulations for calculating tissue‐induced power loss.…”

Electrospinning for the manufacture of biosensor components: A mini‐review

“…Figure 2 shows the process in which biosensors operate. Transducer manufacturing at a smaller size allows for superior signal detection and higher sensitivity which can be utilized with novel user interfaces such as portable smart devices (Honjol et al, 2020; Lopez et al, 2020).…”

Development of an Implantable Capacitive Pressure Sensor for Biomedical Applications

“…Pressure sensors are becoming increasingly important in a wide range of fields, such as automotive, aerospace, industrial, and robotics applications. In particular, pressure sensors are crucial in biomedical applications, including diagnostic health monitoring and precision surgery [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. A good example of this case is intracranial pressure (ICP) monitoring.…”
