Abstract :
We have developed a prototype of battery-powered implantable image sensor unit and successfully demonstrated its operation in phosphate buffered saline (PBS) solution as simulant body solution. We have also proposed its equivalent circuit model for circuit simulation. The transmitted signal waveforms are in good agreement with the simulation result by using the model. The images taken by the implantable image sensor has been recovered from the signal received outside PBS solution.
