Скачать или смотреть Battery-Free Medical Implants | Celtro’s Energy Harvesting Breakthrough using Cadence Tools

Learn how Celtro develops battery-free medical implants using Cadence tools to harvest energy from the human body, reducing pacemaker size and surgery risks.

This technical spotlight provides Biomedical Engineers and Low-Power Chip Designers with a blueprint for disrupting the MedTech industry by replacing chemical batteries with biological energy harvesting.

The Evolution of Bio-Electronic Energy Harvesting In the world of Intelligent System Design, the most significant constraint for Medical Implants has always been the battery. Traditional Pacemakers are composed of 60% to 80% battery volume, which limits their placement and mandates risky replacement surgeries. Celtro is pioneering Battery-Free Technology by developing systems that perform Energy Harvesting from the Human Body. By capturing electrical energy directly from biological cells, Celtro allows for a dramatic Miniaturization of Devices, enabling implants to be placed almost anywhere in the heart.

How this information was derived?
This breakdown features insights from Celtro’s design team, detailing their 20-year history with the Cadence Design Systems environment to achieve silicon success.

Semiconductor Innovation at the Nanowatt Level The ability to harvest and dispense energy at the Nanowatt Level is the "true innovation" driving Celtro forward. This requires a highly specialized Digital IP Core Development process. Using a unified Cadence flow, the team managed their Test Chip from conception to tape-out:

• Spectre Simulation Platform: Used for high-speed, accurate analog simulations to ensure biological interface convergence.

• Xcelium Logic Simulator: Provided mixed-signal verification to validate the digital control of harvesting circuits.

• Genus & Innovus: Facilitated the synthesis and layout generation for the Digital IP Core.

• Tempus Timing Solution: Ensured final timing sign-off for ultra-low-power operation.

Q&A for Medtech Engineers :

1. How do battery-free pacemakers work?
They utilize specialized semiconductors to harvest energy from the electrical potential of biological cells, eliminating the need for a stored chemical charge.

2. What is the main advantage of removing the battery?
It reduces device volume by up to 80% and eliminates the medical Risk Reduction in Surgery associated with battery replacement procedures.

3. Why is Cadence used in this medtech flow?
The integrated environment allows for fast turnaround times and standardized data transfer between analog and digital tools, which is critical for complex Healthcare Innovation.
