Periodic Reporting for period 1 - PepZoPower (Novel bio-inspired energy harvesting and storage all-in-one platform for implantable devices based on peptide nanotechnology)

Okres sprawozdawczy: 2022-12-01 do 2024-11-30

Podsumowanie kontekstu i ogólnych celów projektu

The PepZoPower project sets out to address a pressing challenge in the realm of Active Implantable Medical Devices (AIMDs): the limitations of conventional lithium-ion batteries as a power source.
These batteries, while providing sufficient energy for devices such as pacemakers, implantable cardioverter defibrillators, and neurostimulators, suffer from significant drawbacks.
They require periodic replacement surgeries due to their limited lifespan, which not only poses serious health risks to patients but also imposes substantial economic burdens on healthcare systems.

The project aims to revolutionize the power source for implantable devices by developing a biocompatible, self-powered energy harvesting and storage system.
The core innovation lies in its use of piezoelectric peptide-based assemblies, which convert mechanical energy from natural body movements, such as heartbeats, into electrical energy.
This energy is then stored in a peptide-based supercapacitor, creating a compact, flexible, and autonomous power device.
By eliminating the need for chemical batteries and their associated challenges, PepZoPower has the potential to extend the lifespan of AIMDs, improve patient outcomes, and reduce the frequency of invasive replacement surgeries.

The broader objective is to integrate this novel technology into the growing landscape of implantable devices, addressing unmet needs in both clinical and market contexts.
The project leverages advanced biomaterials and builds on previous breakthroughs from the ERC-AdG-BISON and ERC-PoC-PepZoSkin projects. PepZoPower envisions creating a sustainable and scalable solution, adaptable to various applications such as spinal cord stimulators, cochlear implants, and artificial hearts.

The anticipated impacts of this project are substantial:

Economic Impact: By extending the operational lifespan of AIMDs, PepZoPower reduces costs associated with replacement surgeries, complications, and hospital readmissions. It positions itself as a cost-effective solution for healthcare providers and national health systems.
Healthcare Impact: Patients benefit from fewer invasive procedures, reduced risk of complications, and improved quality of life. The biocompatible and flexible design ensures compatibility with dynamic biological environments.
Technological Advancement: The project introduces groundbreaking energy solutions for biomedical applications, paving the way for new innovations in implantable devices.
Environmental Sustainability: By replacing toxic lithium-ion batteries with biodegradable and recyclable materials, PepZoPower contributes to a greener and more sustainable medical industry.
In summary, PepZoPower addresses critical gaps in the current AIMD market while setting the stage for transformative advancements in biomedical technology. It not only tackles existing limitations but also opens doors to next-generation implantable solutions, profoundly impacting patients, healthcare systems, and the global medical device market.

Prace wykonane od początku projektu do końca okresu sprawozdawczego oraz najważniejsze dotychczasowe rezultaty

The project developed and optimized the PepZoPower technology, an effective autonomous energy harvesting and storage system for biomedical applications. to achieve the challenging integration of piezoelectric energy harvesting and peptide-based energy storage, significant advances were made in both components. The piezoelectric layer was optimized by fine-tuning the crystallization processes, enhancing charge-generation capacity while ensuring mechanical properties were aligned with biological tissues. The energy storage system was improved by utilizing aromatic peptide assemblies to create high-surface-area structures, boosting capacitance and charge retention. These components were then integrated into a hybrid device, where piezoelectric energy was converted and stored in supercapacitors, with rectifier efficiency playing a crucial role in ensuring stable energy storage. The project demonstrated the system’s readiness for biomedical applications, highlighting its potential for wearable electronics and self-powered devices. Through systematic optimization and integration, the technology approached TRL 3/4, paving the way for future biomedical use.
