3D resins for 3D printed bio sensors
3D printing of sensors for biomedical applications has some advantages, such as rapid fabrication, easy accessibility, processing of varied materials availability and bio compatibility and sustainability.
Sensors for monitoring purposes have been used for robotics in the automated industry, aeronautics and aerospace, as well as for wearable sensor systems used as biomedical devices to analyse the physiological parameters of human beings and in the manufacturing industry to detect and monitoring changes of the environment.
Silicon-based sensors have traditionally been used as semiconducting sensors for monitoring industrial and environmental non biomedical applications, including micro and nano-sensors. Their main disadvantage lies in their non-biocompatible nature, which makes them unsuitable for biomedical applications. Fully biocompatible sensors are required for biomedical and implantable applications.
For flexible sensors, a wide range of processing materials have been processed to fabricate prototypes for different kinds of applications. Different 3D printed resins or polymers containing carbon nanotubes (CNTs), graphene and gold nanoparticles can be designed to print sensing electrode prototypes. 3D printed prototypes can be custom designed with different 3D resins compositions and electrodes to meet specific electrical, mechanical and thermal properties.
Fabrication of sensors by 3D printing permits easy and fast customisation and requires less steps than conventional techniques like photolithography or screen printing.
3D printed sensors are more durable and can exhibit superior mechanical strength.
Other advantages of 3D printing is based on its simplicity, speed, automation and low waste generation and risk mitigation.
The 3Dresyns team has the expertise to custom design 3D resins for printing bio sensors with these features and benefits:
- excellent mechanical properties with tensile strength up to 70 mPas or higher
- excellent printability on 3D SLA, DLP, LCD and inkjet printers
- engineering, biomedical and elastic grades
- "monomer free" biocompatible functional materials with no pictograms
- tough, flexible, soft and elastic grades
- elongation <1-10% and up to 100%
- very high resolution
- very low shrinkage
- organo-tin free
3D printed bio sensors can be custom designed to measure physiological parameters such as:
- brain activity
- blood pressure,
- heart rate
- skin temperature
Our capabilities include the incorporation, wettability, dispersibility and stabilisation of a broad range of nano and micron particle size materials, in both powder and/or liquid form of different polarities, from hydrophilic (polar) to hydrophobic (non polar), in our specific custom designed SLA, DLP, LCD and inkjet 3D resins, as the ones highlighted in the following reviews:
