ABSTRACT
This chapter examines what the targets of biological information sensing are. It summarizes the requirements of system on a chip (SoC) for biomedical information sensing. The chapter introduces a urinary disturbance examination system as a specific example of biomedical information sensing systems. This system measures urine flow quantity. Ambulatory urodynamic monitoring (AUM) has become an established method for diagnosing lower urinary tract symptoms (LUTS) attributed to underlying causes such as neurogenic bladder, prostatic hyperplasia, and malignancy. AUM is expected to be able to reduce artifacts and investigate the natural activity of the urinary system in daily life, because AUM releases patients from stressful environments. Medical Domain-Specific system on a chip, Type 1 (MeSOC-1) is designed for having two functionalities: measurement of inner bladder and rectum pressure, and transmission of pressure information. MeSOC-1 is composed of a digital circuit block and an analog circuit block.
