A stent based in-vivo bio-sensing system for glucose monitoring

In this paper, a stent based in-vivo bio-sensing system for glucose monitoring is introduced. Conventional glucose monitoring methods suffer from pain, inconvenience, and financial consumption. In order to overcome the problems, the method that the monitoring system is inserted into blood vessel and detecting the glucose level wirelessly is proposed in this paper. The system includes several blocks such as a sensor interface circuit, a communication block, a wireless power transfer block, and an antenna block. To implement the communication block, a delay locked loop (DLL) for an oscillator is designed and experimented. Also, to implement the wireless power transfer, rectifier and regulator are designed.
