brought together in the topic of bioelectronics, which can be used to establish a bridge
between electronic devices and biological science, potentially opening up new technology
for medical advancement. Bioelectronics, a rapidly expanding area of medical research,
relies heavily on multidisciplinary technology development and cutting-edge research in
chemical, biological, engineering, and physical science as shown in Figure 1.1. For ex
ample, features of bioelectronics components such as potential, impedance, and charge
transport may be monitored to determine the source of a bioreaction by analyzing its
surface resistance or resonance frequency, among other things. When a biological event
happens, the electronic materials may be used to test how well they work in the presence
of the event. With electrical components, it is possible to develop a second sort of bioe
lectronic system, which aids biomaterials in performing their activities. Likewise, bio
sensors capable to transform biological processes into electrical signals create a new
domain in bioelectronics. Because of these advancements, bioelectronic scientists are in
venting numerous gadgets for replacing ill-fated body parts to offer humans a new life to
live. Using artificial body parts, these technologies can recognize complex brain impulses
and translate them into normal physical actions. In addition, these newly created bioe
lectronics devices are potentially able to sense various abnormalities to alert the immune
system to prepare for designing a defense protocol. At the molecular, cellular, tissue, and
system levels, our understanding of biology and the basis of illness is rapidly improving.
In the coming years, as semiconductor devices shrink and become more useful,
scientists expect to develop implantable prostheses that improve quality of life, lab-on-a-
chip tools that enable sensitive and selective detection of infections, biomarkers for
diseases, portable and cheaper imaging tools. However, the aging population in affluent
nations, rising healthcare costs, and limited access to medical treatment in less developed
and rural areas are driving demand for new developments in this sector. On the other
hand, it has become increasingly important in recent years to investigate and build
bioelectronic circuits. Incorporating similarities between biological processes and elec
tronic circuits or combining biomaterials with electrical components can be used to de
velop these circuits. A bioelectronic system is designed such that electronic components
may be utilized to steer biomaterials toward their intended uses. Biomaterials may be
created by genetic engineering or bioengineering, allowing for the generation of novel
enzymes and protein receptors, as well as the manufacturing of monoclonal antibodies or
aptamers for non-biological substrates such as metals and metalloids. These materials and
electrical components can be mixed in a variety of functional units to get the desired effect.
