Health of the public is one of the important factors which influence the wellbeing state of a human being. The diagnosis of any chronic disease or disorder & to develop treatment for that particular diseased condition is only possible after the involvement of medical devices & combination products which wasn’t possible in previous years. The detailed differentiation of medical devices is based majorly on the risk factor involved from low risk to that of high one. To get the better understanding regarding all the medical devices the regulations prevailing to particular device can be studied. The goal of developing medical device regulation systems is to protect public’s health while also ensuring their safety & performance. These regulations of medical devices products are governed by FDA which also monitors the safety & efficacy of all medical products. Innovation further leads to manufacture of new medical device. As the pharmaceutical sector & engineering department work hand in hand which has played a vital role in the physiology of organs, better performance, & better life span & in complete replacement of that particular organ system.

The broad art of uses of nanomaterials or nanoparticles and nanodevices that are used in medical healthcare to diagnose and cure a variety of diseases has recently developed as a result of recent advancements in pharmaceutical research.So, in this review article, we will discuss the various art of nanomaterials that are used in various forms to develop various nano-devices and nano technologies that are widely used in medical applications, such as cantilevers, which are highly stable devices that are integrated into highly sensitive disease markers in diagnostic detectors and display reliable performance for a long time. These nanoparticles are also employed in the creation of various dosage forms that are used to either cure or diagnose diseases. These nanotechnologies are frequently used as sophisticated tools or gadgets in the early identification of cancer and atherosclerosis in the human body, where subsequent therapy such as nano-surgery may be used to cure them. These are well-known superior materials that are necessary for many fields due to their nano size.

Stimuli‐responsive materials can frequently tune between their temporary and original shapes, and have the potential for artificial intelligence‐based technologies in robotics, aerospace, biomedical, engineering, security, etc. Shape memory polymers (SMPs) are promising for these technologies but their inadequate thermal and electrical characteristics causing slow shape recovery limit their practical applications. Herein, for the first time, comprehensively and precisely the shape memory polyurethane (PU), a promising SMP, via a variety of novel layered titanium carbides fillers, namely, Ti2AlC (MAX1), Ti3AlC2 (MAX2), and Ti3C2 (MXene), is engineered. The resultant PU‐composites show 30–50% faster shape recovery in different environments, 20–25% greater extent of shape recovery in the load‐constrained environment, 100–125% higher thermal conductivity, and 700–16 000× higher electrical current. Importantly, the reinforcement of even a small amount of MAX and MXene (such as 0.25 wt%) has largely boosted the performance of PU. Considering ease of processability and performance enhancement factors, the MAX‐phase fillers may be preferred over MXene‐phase fillers for next‐generation composites development. Employing PU composite component as both heat‐sensor and actuator, a unique heat detector/fire alarm device that works successfully in simulated heat and fire environments is demonstrated. This work is crucial for enabling futuristic technologies.
