The NORIKA system is a novel battery-free micro capsule endoscope. Wireless power and external processing eliminate battery risks, enabling longer, safer internal examinations.

Area of Science:

  • Medical Devices
  • Biomedical Engineering
  • Wireless Power Transfer

Background:

  • Traditional capsule endoscopes rely on batteries, posing risks of toxic leakage and limited operational duration.
  • High power consumption of Charge Coupled Device (CCD) sensors in capsule endoscopes necessitates innovative power management solutions.

Purpose of the Study:

  • To develop a battery-free micro capsule endoscope (NORIKA system) for safer and longer internal examinations.
  • To address the power consumption challenge of CCD sensors by relocating the Digital Signal Processor (DSP) externally.

Main Methods:

  • Wireless power transmission using microwave technology and a coil-embedded vest.
  • External processing of CCD sensor data via a Digital Signal Processor (DSP) to reduce capsule power draw.
