With the advancement in technology, there is a rapid progress in the field of sensors and instrumentation for various applications in different fields. From macro to micro- and nano sensors, the development is discussed here. Main emphasis is placed on the development of ubiquitous sensors for better health care, at a low cost  but in a reliable and effective manner.

Ubiquitous technology has captured the convergence between the technological fields and their implications for the economic, political and social aspects of society. The ubiquitous computing with computer devices embedded in everyday objects invisibly at work and the environment, gives intelligent and intuitive interfaces making  computer devices simple to use and unobtrusive. The sensor networks connect these devices together to facilitate measurement anywhere, anytime, always-on communications. The use of mobiles, internet and RFID chips has played major role in connecting the people to communication devices globally. The automatic and autonomous collection of data from the inanimate to visible objects in the environment, has created truly intelligent and ambient network spaces, including health environment.

Main thrust is also on the development of new sub-systems, nano technologies and smart systems to make them ubiquitous, to evolve a revolution of telecommunication. New biomedical ubiquitous health care systems particularly for patients in remote areas and hills are developed.

Design and development of biomedical ubiquitous sensors for healthcare are presented, with main emphasis on U-health care technologies like e-health, biomedical sensors and sensor networking, involving mobiles, internet or RFID technology. New diagnostic and therapeutic devices by using RFID chips, nano-scale or sensor-enabled radio technologies and sensor networks for solving the problem of unexplored diseases in future, and controlling of the quality of medicines, drugs, equipment and physiological event monitoring systems, are also highlighted.
