Digital Twin the emerging and forefront in engineering revolution especially Industry
5.0. It simulates the industry environment and IoT connectivity. IoT enables smart connectivity
in various engineering applications and medical applications. It strongly coupled with data
science and analytics to handle large amount of data connected with sensors and devices. It also
handles virtual environment with low cost but the challenges are complex. This paper analysis
the technical issues faced when implementing digital twin model practices in engineering and
medical applications.
