This paper presents the result of study on the development of a bladder volume sensor. Previous studies focus on the development of an inner bladder pressure sensor. But there are some difficulties about the measurement of pure inner bladder pressure. A bladder volume sensor detects change of bladder volume. A measurement of volume changes is able to find a condition of patient through correlation between a bladder volume and a urine volume. A bladder volume sensor is a capacitive sensor. A sensitivity of bladder volume sensor is 0.41㎊/㎜. The purpose of this paper is an aid for the treatment a dysuria patients.
