An ultra-stretchable triboelectric strip sensor (TSS) to control objects in 3-D space
Nanogenerators, technological tools that can convert mechanical or thermal energy into electricity, come in three key designs: piezoelectric, triboelectric and pyroelectric. While piezoelectric and triboelectric nanogenerators can convert mechanical energy into electricity, pyroelectric ones work by harvesting thermal energy.
