Stretchable strain sensor based on HfSe2/LIG composite with high sensitivity and good linearity within a wide range

HfSe2/LIG composites were prepared for the first time using a straightforward procedure. And the HfSe2/LIG strain sensor demonstrated excellent sensitivity (GFmax=150), low detection limit of 0.02% and great tensile durability (>3000 cycles), which indicates it has potential applications in healthcare applications and tracking human movements.
