changing in a smaller portion of space like in multilayer logic circuits. Low mobility of
electrons in semiconductors, high operating voltage, and stability of transistors are still
problematic. In the future, advanced materials may solve these problems. Low mobility
of ions in an artificial synaptic transistor helps them to make a high degree of mimicry.
In dielectric layer output, signals are in the form of time information, yet the process of
decoupling of information is still unclear. There are various methods for reading and
processing signals to cope with the situation. In all of these methods, electronic skin
sensors are distributed and mixed with skin in a prosthesis. Event-based coding is an
efficient method that is closest to the nervous system. The asynchronously coded
electronic skin technique allows the terminal to access the 10,000 sensors simulta
neously. In this technique, low constant latency of 1 ms and a power supply of high
precision is required that make these receptors larger compared to the receptors of
human subcutaneous.
MCUs in combination with wiring signals can achieve the arrays sensor of high density.
However, numerous wires required for this technology make its implementation chal
lenging. Mismatched integration of rigid chips with flexible electronic skin is still a dif
ficult task. The size of the receptors can be decreased with the application of specific
integrated circuits. New methods and devices that work on new mechanisms enable in-
situ coding in further investigation. The transmission of signals through digitized elec
tronic skin still needs to be explored. Some electronic skin implements optical technology
or wireless methods for signal transmission while most of the electronic skin uses direct
signal transmission. Sensor arrays are frozen in wireless technology by bound wires.
Traditional wireless networks for electronic skin rely on radio-wave communication.
These networks provide inefficient energy and are vulnerable to eavesdropping. A
wireless network of body sensors is an alternative to fill the above shortcoming. This
network is propagated at the surface of textile made of metal material. It is connected
through radio surface plasmons. This metal-based material is used to improve the se
curity and efficiency of transmission of the signal. These transmit the signal from different
parts of the body from different multiple sensors in a wireless way. This may be fruitful in
the prosthesis. Associated receivers and receptors rely on the chips. These are still
compared with the sensory units of humans. There will be a new trending way for de
veloping the new methods of signal transmission to decrease the difficulties created by
numerous wiring.
Polymers materials are stretchable and flexible. These are used for manufacturing the
new designs of bioinspired devices. These materials can stimulate the neurons. Then,
these record the signals and activate the prosthetic action or body. Implantable neural
interfaces that are early discussed can represent the mesh electronics and implantable
probes that are deeply embedded. This embedding helps accurate stimulation and re
cording at a specific region of the brain. These probes and electronics are biocompatible,
small, and have a minimal immune response to glial infections. Actuators in combination
with sensors respond to light, heat, and electricity. These provide multifunctionality in
these probes and are used to monitor the pH, glucose, and oxygen in the blood.
Mesh electronic interface, together with optical waveguides based on polymer mate
rials, can pursue the stimulation in deeper tissues of the brain matter. Until now, a large
variety of sophisticated bioelectronics has been developed. However, these devices still
face many challenges. A highly functional prosthetic system is required that corresponds
to the sensory feedback. The dexterity of human skins can be achieved by integrating
the higher level of devices. These high levels of devices provide a variety of a large
number of mechanoreceptors. These devices are embedded in the human skin. In
