Design and evaluation of an implantable MEMS based biosensor for blood analysis and real-time measurement

Detection and measurement of specific molecules in person's blood is always important in determining his or her health status. Immediate diagnostic methods are essential in this regard, especially when a particular disease is spreading. In this paper, an implantable and real-time molecule detector is proposed for blood analysis which is possible to fabricate using Micro-Electro-Mechanical Systems (MEMS) technology. Inspired by mechanical resonator sensors which are proposed to droplet analysis for lab-on-a-chip applications, a design based on a micro-mechanical resonator is proposed in this work as an implantable biosensor. It can be used inside a needle and its application is suggested in this paper. In order to evaluate the quality of the proposed design, simulations are performed by COMSOL and the results are presented. Also, the fabrication method of this design is presented.
