Effect of the secondary microcontact state induced by the all-factor thermal effect on bidirectional thermal contact performance

Investigation of the surface mechanical properties of functionalized single-walled carbon nanotube (SWCNT) reinforced PDMS nanocomposites using nanoindentation analysis

“…In applications where PDMS–SWCNT composites are used as sensors or actuators, the contact stiffness affects the sensitivity and responsiveness of the material. 86–88 S c is estimated by fitting a regression function to the upper part of the unloading curve. It is correlated using the following equation. S c = 2 βA c π E r where β is a constant that depends on the geometry of the indenter ( β = 1.034 for a Berkovich indenter).…”

“…Improvement in surface mechanical properties such as contact stiffness ( S c ) is crucial for the reliable sensitivity of PDMS–CNT-based wearable sensors. 86–88 In addition, PDMS–CNT-based lab-on-a-chip devices and flexible microfluidic systems rely greatly on the elastic modulus and viscoelastic mechanics of the material system. 92–96…”
