Additive Manufacturing of Physical Sensors for Biomedical Applications: A State of the Art Review and Future Research Prospective

Abstract

The biomedical sensors are the electronic devices which converts the biomedical signals into electrical signals for measurement of biomedical activities. The additive manufacturing is one of the proved technologies for the manufacturing of functional as well as nonfunctional prototypes. The additive manufacturing processes in form of various technologies have been reported for the preparation of sensing structures. The among the different biomedical sensors such as; physical sensors, chemical sensors, bio-potential sensors and bio-analytic sensors, the additive manufacturing of physical sensors have been widely reported by previous studies. The physical sensor includes sensors includes sensors such as; geometric, mechanical, thermal, hydraulic, electric and optical sensors. The present study is a state of the art review for the preparation of physical sensors by additive manufacturing processes. This study highlights the overview of previous studies and direction for future studies for manufacturing of physical sensors by additive manufacturing approach.
