Use Case: Micro Battery for Capsule Endoscopes Capsule endoscope Capsule endoscope is a non-invasive method for examining the gastrointestinal tract, particularly areas such as the small intestine that are difficult to access with conventional endoscopes. The patient swallows a small capsule equipped with a wireless camera, which captures thousands of images as it travels through the digestive system. These images are transmitted to a recorder worn on the waist, enabling detailed visualization and improved diagnostic accuracy with minimal discomfort. Challenges in capsule endoscope battery design:...

Development of High-Drain SR Batteries for Smart Pills Smart pill Comparison of discharge performance Smart pills are capsule-shaped oral devices that deliver drugs and collect biometric data such as temperature, pH, pressure, and images as they move through the digestive tract. Multifunctional sensing requirements Stable power and support for peak current loads are essential for multifunctional sensing, including monitoring of pH, temperature, and pressure. Safety and reliability for internal use Batteries must be safe and reliable for use inside the human body. Miniaturization for swallowability...

High-Drain SR Battery for Smart Pills (Developed Model) With SR927 (Ø9.5mm × 2.73mm), this technology supports ~100mA and maintains higher voltage throughout discharge than standard cells. CCV comparison during pulse discharge Test condition: 20 ゜C Minimum transient voltage observed when a 100 mA, 100 ms current pulse is applied 10 times to each test cell at 20°C. Note: • Both models shown are high-drain type (W) SR batteries. The comparison includes a conventional model and an improved prototype. • The values shown in this document are experimental results for technical comparison purposes and...
