Review—Power Approaches for Biosensors based Bio-Medical Devices

Abstract

Health care industries are progressing towards improving the health condition of the society, by developing new medical devices with innovative technologies. The advancement in medical technology has brought to reality developing sensor-based medical devices, which are implantable as well as wearable. The present challenge is designing in terms of low noise, low power, low area design techniques, considering patient safety and for a long term process these devices are getting more prevalent in the society. Addressing the problem of battery drain in Implantable Medical Devices (IMD) to the replacement of IMDs and additional surgeries would be the solution due to that. This survey paper presents a glimpse of a deep survey done on various types of power approaches that are carried out on Implantable Medical Devices focusing on extending their durability and attempts done to design various types of amplifiers and converters for sensors used in different medical devices.

Microfluidics-Based Nanobiosensors for Healthcare Monitoring

“…In one of the research the extremely selective paper-based amperometric biosensor have been developed which can analyze choline in clinical samples from patients suffering from renal diseases and receiving repetitive haemo-dialysis treatment [ 106 ]. These nanobiosensors have been classified as dipstick, lateral flow assays (LFA), and μPAD based on their utility [ 107 – 110 ]. However, the only constraints associated with these biomarkers are their thermal instability and requiring specialized storage [ 111 ].…”

A 0.8 V, 14.76 nVrms, Multiplexer-Based AFE for Wearable Devices Using 45 nm CMOS Techniques

“…It is possible to find the perfect transistor size for a given set of requirements by using optimization techniques. Transistor sizing is often required for a number of performances, including the transconductance parameter of the NMOS, PMOS (k n , k p ) Equations ( 3) and ( 5), and the transconductance of the NMOS, PMOS (g mn , g mp ) Equations ( 6) and ( 7) [40]. This is used to analyze the OTA's power consumption, gain, frequency response, and linearity [41].…”
