Data Fusion of Contact Sensors for Soft Actuator Angle Measurement [PDF]
The existing contact sensors for soft actuator angle measurement mainly include inertial sensors and curvature sensors. However, the measurement accuracy of inertial sensors is easily affected by the expansion of the airway embedded in the soft actuators,

Heat and Mass Transfer Processes and Evaporation of a Liquid Droplet on a Structured Surface
The characteristics of water droplet heating and evaporation on structured hydrophobic and hydrophilic surfaces in the range of static contact angles from 73° to 155° were studied experimentally using high-speed video recording.

Theoretical analysis for dynamic contact angle hysteresis on chemically patterned surfaces [PDF]
A dynamic wetting problem is studied for a moving thin fiber inserted in fluid and with a chemically inhomogeneous surface. A reduced model is derived for contact angle hysteresis by using the Onsager principle as an approximation tool.

The Possibility of Changing the Wettability of Material Surface by Adjusting Gravity
The contact angle, as a vital measured parameter of wettability of material surface, has long been in dispute whether it is affected by gravity. Herein, we measured the advancing and receding contact angles on extremely low contact angle hysteresis ...

Development of a Contact Force Model Suited for Spherical Contact Event
The stiffness coefficient suited for a spherical contact body is developed by means of a contact semi-angle based on Steuermann’s theory. The new static contact force model is close to the results of FEM when the index of the polynomial is equal to 2 ...
