Figure 1From: Cracked titanium film on an elastomeric substrate for highly flexible, transparent, and low-power strain sensorsSchematic process to fabricate a cracked Ti film on a PDMS substrate. Step 1: preparation of a PDMS sheet, step 2: slicing of the PDMS sheet into 26 mm × 8 mm-sized samples, step 3: deposition of a Ti thin film on the PDMS substrate, and step 4: generation of cracks by mechanical stretching.Back to article page
