A Wireless Soft Optical Blood Sensor for Colonoscopy
Colonoscopies provide essential diagnostic capabilities, helping detect colorectal cancer (CRC) and inflammatory bowel diseases. However, visualization of the clinical workspace is limited to the distal tip camera. Thus, bleeding behind the tip can go undetected and pose safety risks to patients. This work presents a wireless soft optical blood sensor as an “add-on” device for the colonoscope, utilizing light attenuation for bleeding detection. The multiple-sleeve sensor design is made of microelectronic components with a flexible printed circuit board (PCB). The blood detection capability is characterized by various blood analog concentrations. The data rate, latency, and signal-to-noise ratio (SNR) are investigated to ensure the quality of real-time bleeding detection and effective data transmission. The wireless blood sensor successfully performs in ex vivo trials without breaking down throughout 40 trials in three novices and one expert user.
