1. Metallic microstructures can be fabricated by injecting liquid solder into PDMS microfluidic channels.
- Breaks in these microstructures can be repaired by heating and sonication
2. Has anyone at VIIBRE or SyBBURE tried this?
In addition to electronics, what are other uses for these metallic microstructures?
3. Other methods for fabrication of metallic microstructures.
4.
1. This article contains techniques for microfabrication, specs on the materials used, and applications for microstructures such as flexible electronic circuits, 3D electronic components, and hybrid electronic microfluidic devices. The article also includes a supplemental experimental report, which lays out the procedure for many of these techniques.
ReplyDelete2. Could any of these techniques be used for direct medical application, such as the fabrication of surgical devices, reconstructive surgery, or microsurgery?
3. Applications of Microfabrication for Neurosurgery
4. Wonder if these methods are used in the construction of electrodes or microsurgical tools?

1. The novel technique of microsolidics can be used to create metallic microstructures that are embedded in PDMS. The microstructures can be used with microfluidic channels in the same device.
2. Does the solder diffuse into the PDMS? Will structures that have been bent retain their new shape if the PDMS is removed?
3. Applications for flexible electronic circuits
4. Does the solder change the chemistry on the surface of PDMS channels?

1. Learned: Filling PDMS channels with molten metal is one way to make small 3D micro-structures.
2. Pressing ? : Does the process of releasing the microsolidic structures destroy the PDMS?
3. Presentation: Nothing in particular I can think of. Just tell us how cool this process is.
4. Thoughts: Is anyone currently employing this awesome process in their projects?

1. You can create 3D metallic structures by pumping solder into PDMS and bending the structures before removing the PDMS.
2. I wonder if this can be done with materials other than solder.
3. The possible uses of microsolidics
4. This is a pretty cool/original way to use PDMS

1. Learned: PDMS microchannel devices can be used to mold metal into tiny, cool shapes
2. Pressing ? : I don't really get why this is called 3D. What's the difference between this and other metal work? Will the metal retain its shape once the PDMS is removed?
3. Presentation: Applications of these tiny metal structures
4. Thoughts: Cool

1. Using microfluidic devices to produce "microsolidics" by injecting solder into the channel. Produces flexible, thin metal.
2. Why doesn't the solder melt the PDMS? Could some metals not be used with this technique?
3. Application of microsolidics to some SyBBURE projects. Anyone have a project where this would provide a new thing to branch out on?
4. Surprisingly simple and effective. I'm shocked none of us thought of this.

1. PDMS microfabrication techniques can be used to develop complex micro-metallic circuits with 3D flexibility
2. How could this technology be used with microfluidics to improve current SyBBURE applications like the cell-trapping PDMS device?
3. Potential benefits of nanoscale microsolidics over microscale microsolidics

1. 3D metallic microstructures can be fabricated by injecting liquid solder into PDMS channels.
2. What are the more material properties of solder, would the wire break under extreme torsion, would it bend and deform permanently even inside the PDMS?
What is the conductivity of the PDMS, is it posible to have a current/ voltage so great that it would shock through PDMS or maybe melt the PDMS
3&4. Maybe this concept could be incorporated into the construction of prostetics by minimizing the space the circuitry required and by reducing the risk of getting shocked. It would be worth looking up

1. Flexible 3D microsolidic devices can be made and repaired using liquid solder and PDMS. These devices are easier and more practical to make than using previous techniques.
2. How do these microcircuits interact with human tissues? Could they be incorporated into small-scale biomedical devices?
3. Microcircuitry and artificial muscle stimulation and coordination
4. I think it would be very cool if somehow these tiny circuits could be used for mass muscle stimulation in paralyzed people.
1. PDMS could be used as a mold to make metallic microsolids.
ReplyDelete2. Is there a way to preserve the PDMS for continuous molding?
3.Uses of microsolids

1. fabrication of novel 3D "microsolidics" with PDMS
2. how does the process affect grain size in the metals, also how does the process affect the surface properties of PDMS
3. Presentations on semi conductor CVD
4.how well controlled can the microenvironment get in the process, it sure seems like it would cool pretty heterogeneously.

1. Flexible 3-D metallic microstructures can be produced by flooding PDMS microchannels with solder
2. The authors say they dissolved the PDMS and coated the solder with copper; would it be possible to coat with platinum for biosensing devices?
3. Presentation on microsolidics and applications
4. Would there be any concern that electrical current through these wires would burn the pdms? They didn't seem very conductive.
