Making a Wire Lithograph and Pressure Sensor Nanotechnology Kit


Developed in partnership with Argonne National Laboratory.

  • Designed for 10 groups of 4 students
  • Includes instruction manual
This kit gives your students the opportunity to apply a revolutionary nanotechnology manufacturing technique to grow nano-scale and micro-scale copper wires. Using a unique ultra nanocrystalline diamond (UNCD) electrode, students use traditional electroplating and lithography (E&L) techniques to grow pattern-shaped wires that become the essential components that can be used to fabricate optical and electrical sensors and other devices.



This kit covers the following concepts: measurement scales/perspectives, unique properties at nanoscale, fabricating nano/microscale structures, and creating nano/microscale lithographic wire patterns.



Activity 1 - Making a Wire Lithograph

(GUIDED – MODEL EXPERIMENT)

Students incorporate the UNCD electrode in a traditional electroplating apparatus and apply a 9V potential to electroplate star wire patterns. Depending upon electroplating time (minutes), students create and transfer invisible (nanoscale) or visible (microscale) wires in a star pattern onto sticky tape. In the process they learn directly about scale (nano to macro) scale prospective. Your students observe these wire patterns placed on microscope slides under low (100X) magnification. They assess how electroplating time (electro deposition) affects wire length (and corresponding wire pattern visibility) and how wire patterns can be consistently produced and reliably transferred onto a flexible support medium (sticky tape). These learned skills form the basis for future student design applications – such as incorporating copper wire lithographs into sensors or creating light diffraction gratings.



Activity 2 - Making a Conductive Pressure Sensor

(GUIDED – INQUIRY EXPERIMENT)

Students apply their knowledge of nanomanufacturing (E&L) to create nanowire and microwire patterns that can be used to create a pressure sensor. Students learn what a sensor is and use their observational electro-deposition data (from the previous activity) to design, manufacture, and test a conductive ‘bridge’ (pressure ‘sensor’) allowing illumination of a 9V LED lamp.
