medical marking

医療機器のレーザーマーキング

The Industry 4.0 paradigm makes it a necessity to track the functionality of each single device and to avoid counterfeiting. This is critical in the medical industry when a patient's condition is on the line. To combat this, cloud based individual tracking systems and highly advanced marking techniques must be employed. The Nanofactory allows the production of QR codes down to several micrometers on arbitrary material. Devices suffer no thermal damage or other side-effects outside of the marking area, crucial for maintaining functionality of medical device / components after marking.

femtika microfluidics

マイクロ流体力学

When liquid is confined within extremely small spaces (several hundred micrometers), non-trivial behavior can be exploited for drug development/production, life-sciences, fundamental research, and more. Amplified femtosecond lasers have been shown to be extremely capable in producing microfluidical components. Realized through both additive and subtractive manufacturing channels, arbitrary free form integrated elements and bonding can be realized with only one laser micro-machining setup.

マイクロメカニクス

With the natural trend of downsizing the mechanics in modern technology, it increasingly important to reduce the size of the mechanical elements. 3D femtosecond micro-manufacturing with the Nanofactory allows sub-micrometer scale elements to be produced. FS pulses allow the possibility of producing elements with a diverse range of materials, from polymers and glasses, dielectric crystals, or metals. Gears, springs, cantilevers, and other classical elements can be easily produced.

Diverse femtosecond processing regimes provide a wide range of benefits. Additive manufacturing of conductive medium becomes possible, allowing true 3D electrical components to be created. Cutting or scribing of electrical contacts is also possible thanks to the minimal heat effects from femtosecond laser processing. The laser can also be used to produce high precision substrates for electronics, cutting any trenches, holes, and any other pattern.

プロジェクト

Project is funded by the European Regional Development Fund, project Nr. 01.2.1-LVPA-K-856, project duration: 2020-2022.

Focused femtosecond radiation allows to selectively induce arbitrary refractive index modulations inside any optical fiber. Additionally, multiphoton polymerization can be used for easy assembly free fabrication of multi-component micro-optical elements on tips of optical fibers allowing to forgo currently used complicated gluing-based multi-step process. Combined,
these two processes will pave the way for a revolution in on-demand fiber-based device manufacturing.

The end goal of the project will be two femtosecond laser-based workstations – one for Brag grating integration into optical fibers and second one for fiber-tip optical element manufacturing.

Prototyping of innovative multifunctional industrial machines for the production of complex microfluidic devices

The aim of the project: to acquire knowledge and form concepts of their application for the development of new microfluidic products for medical and biomedical purposes. Based on them, to develop an efficient technological process for the transfection of microfluidic perforator molecules into cells and the formation of a micro (nano) microfluidic sensor for slow liquid / gas flow. To create prototypes of devices, which will be able to realize the process of laser micro (nano) forming for the layout and production of the mentioned microfluidic products.

During the project implementation period, the following research activities were performed:

1. Investigations of design characteristics and technological concepts of microfluidic channels for cell transfection and fluid flow measurements;

2. Investigations of design parameters and forming concepts of micromechanical components required for cell perforation and fluid flow measurements integrated in microfluidic channels.

Possible essential constructive technological solutions of microfluidic channels were modeled, tested and evaluated during the activity. The optimal solutions have been chosen both in terms of technology, ie simplicity of formation of structures, economy, and functionality in terms of functionality in a medical device. To ensure the functions of the cell perforator, the optimal concept of knives integrated in microfluidic channels was chosen, in the case of a flow meter – the concept based on the use of an electromechanical valve. After refining and finalizing the 3DLL process parameters, it became possible to test and more precisely define the mechanical and optical properties of microfluidic channels and the elements integrated into them, and to use adequate numerical modeling for their design. In this way, it was possible to resolve the scientific uncertainties unknown before the start of the activity.

The objective of project is to develop, test and demonstrate industrial-grade solidstate 2-3 kW-level fs laser with parameters suitable for metal surface patterning for enhanced surface repelling and/or adhesion properties, leading to increased durability, self-cleaning, anti-fouling or enhanced tissue attachment applicable in industrial settings.

FemtoSurf industrial-grade 2-3kW-level fs laser will be integrated in proposebuilt optical chain enabling multi-beam processing (100+ simultaneous beams) with individually tailored spatial distributions in each laser spot, integrated into a fully automated processing setup for efficient patterning arbitrary shaped metal components.

The aim of the project is to deliver the respective enabling technologies of 3D glass micro-nanofabrication for micro chip manufacturing based on a gas handling and delivery system, with an accompanying user interface design for full system automation. The main task is to demonstrate how different geometries and material combinations (metals and oxides) can be combined for production of microchip devices utilised in different types of sensors, e.g. temperature, pressure and capacitive position.

Two types of organic heavy metal free fluorescent materials show exceptional potential for use in new-generation light sources:

i) fluorescence materials exhibiting thermally activated delayed fluorescence (TADF) for use in OLEDs in displays and lighting devices;
ii) fluorescent materials with low thresholds for amplified spontaneous emission (ASE) for use in organic lasers in spectroscopy and telecommunication.
In order to develop these materials for commercial industrial use, the number of the scientific and technical challenges are needed to be overcome.
The overall goal of the MEGA project is to help develop organic heavy metal free fluorescent materials for commercial use by tackling existing scientific and technical challenges.
The aim of the project is to develop an advanced laser beam deflection system for material processing which allows for laser beam positioning pulse by pulse. The system will be able to accelerate several laser processing tasks by a factor of 100 or more. It will be integrated into Femtika‘s next generation Laser Nanofactory workstation. TEM-Messtechnik will develop suitable control equipment. LZH will contribute control and material processing strategies.
The objective of the project is development of the state-of-the-art laser microprocessing by scanning the laser focal point on the material surface. 
The project proposes a new laser lathe approach, including a laser edge interaction, to process objects with rotationally symmetric components. 
For implementation of the project technological and scientific progresses are required on the investigation and application of laser scource, laser shaping, CAD/CAM software, and laser-material interaction.

2) To determine the structural and optical characteristics of the formed elements.
3) To determine the limits of spatial filtration stability of formed elements under laboratory conditions.
4) To confirm the actual operation of the formed elements (prototypes) under laboratory conditions.
The objective of the project is to develop and elaborate feasibility study for Femtika’s developed 3D Micro – nano fabrication device NANOFACTORY commercialization, which would include:
