A medical stimulator has been used for pain relief treatment. But, it cannot deliver stimuli to the target tissue without any affection of other tissues, and, moreover, the undesired stimuli to the patient's heart can cause dangerous heart failure. As a result, the current intensity of stimuli should be limited within proper values. There are available solutions that ensure safety and raise the efficiency of stimulation at a target tissues by designing electrodes and the stimulation waveform. In this paper, we measured and estimated the stimuli transmission through the electrolyte chamber that are simulating the patient's tissue at different conditions that have different values and waveforms and that are equipped with different electrodes. We tried to find the most optimal stimulation condition that can concentrate stimulation energy to the target tissue at various stimuli waveforms according to the design of electrodes. The basic design concept of electrode is that the circular reference electrode block off the leaking current from the stimulating electrode. And, the stimulation waveforms are monophasic and biphasic exponential truncated pulses.

Drug Drug controller is maintain the injected drug rate in body, and it is device for the controls of drug injection accordinng to the condition of patient. More conventional drug controllers were developed, but the most devices were limited to control of drug rate because of control in person patient`s. In the study, Drug controller is developed by thermopneumatic using PDMS. In order to verify the injection rate of drug controller is measured in the pressure change according to the injection rate by in-vitro, and the accuracy is compared with the conventional drug controller.
