Physical Sensors for Biomedical Applications

Abstract

Use of sensors is increasing day-by-day in the real world to improve the quality of life by providing information on medical diagnostics for healthcare. Among numerous emerging sensing technologies, physical sensors "electronic devices" have been successfully demonstrated in the field of biomedical applications because of their excellent operation capability. Physical sensing is a unique sensing platform, where sensing devices are responsive towards physical properties (e.g., radiation, light, flow, heat, pressure, magnetic field, and parameters related to mass or energy) and convert them into signals for quantification. This review paper describes the different physical sensors and their biomedical applications, current main challenges, and future developments.

Monitoring health parameter of remotely located patient

“…Firstly, we have to sense value form physical sensor like here for sensing where AD8232 ECG sensor [6] is used for sensing ECG, MAX 30100 pulse oximeter & heart rate sensor is used for sensing SP02 level in blood and heart rate [8]. This sensed value will be sent to ESP32 Wroom this will manipulate data and using AP mode of ESP 32 this sensed value will be send to database their data will be there for future use.…”

Application of Biosensor

“…Physical sensors are used in biomedical application such as blood pressure, muscle displacement, body temperature, bone growth and cerebrospinal fluid pressure measurement. Physical sensors are used in electronic device such as x-ray tomography, PET, ultrasonography, MRI, measurement of blood pressure and body temperature [8]. Methyl parathion is an organo phosphate insecticide which is used to product crops from insects.…”
