Remarkable piezoresistance effect on the flexible strain sensor based on a single ultralong tellurium micrometre wire

摘要: Flexible strain sensors based on a single ultralong tellurium micrometre wire have been prepared. The sensor device consists of flexible polystyrene substrate with placed its surface and bonded by silver paste. Two types were fabricated. One uses back to Schottky barrier contacts. This has different shape I–V behaviours due the change height when there are no strain, stretch, compressive strains. current increases as increases. second contact. more significantly under compression at negative voltage. By contrast, latter is suitable for detecting
