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.
