 Introduction       Biomechanics  is the study of the structure, function and motion of the mechanical aspects of biological systems, at any level from whole  organisms  to  organs to   cells ,  using the methods of  mechanics .  Biomechanics is a branch of  biophysics .            Arthritis is an inflammation of the joints. It can affect one joint or multiple joints. There are more than 100 different types of arthritis, with different causes and treatment methods. Role of biomechanics Biomechanic s play an important role in the health of diarthrodial joints. Altered joint loading is associated to obesity, malalignment, trauma, or joint instability is a critical risk factor for joint degeneration, whereas exercise and weight loss have generally been shown to promote beneficial effects for osteoarthritic joints. Under physiologic conditions, joints of the body are subjected to million...

 Introduction  What are biosensors? It is an analytical device that detects changes in Biological processes and converts them into an electrical signal  which can be then measured or analyze. The biological material is usually in the form of an enzyme, with the help of a process known as electroenzymatic approach, which is a chemical process of converting the enzymes into corresponding electrical signals (usually current) with the help of a transducer.  The combination of biological element and a transducer will convert the biological material into a corresponding electrical signal. Depending on the type of enzyme, the output of the transducer will be either current or voltage. Biosensors are based on the method of the transduction, which is classified into three  category:- Mass based biosensors Optical based biosensors Electrochemical biosensors Mass based biosensors The mass based biosensors, also known as gravimetric biosensors apply the basic principle of a...
