The present invention discloses an encapsulated duct cable with identification tags and a manufacturing method thereof. The logging encapsulated duct cable comprises an encapsulation layer. The cross section of the encapsulation layer is polygonal or arc-shaped. At least one cable protective tube and at least one oil-liquid tube are arranged in the encapsulation layer. A cable is arranged in the cable protective tube. Identification tags with different color identifiers are respectively arranged on one side of the cable protective tube and one side of the oil-liquid tube in one to one correspondence. The manufacturing method of the logging encapsulated duct cable mainly comprises three steps of machining the cable protective tube and paving the cable pavement, machining the oil-liquid tube, and machining the encapsulation layer. The present invention has double functions of conveying the oil and the liquid and transmitting the data.

A muscle-like actuator comprises a motor with a rotatable drive shaft and a string with a shear thickening fluid (STF) embedded therein. One end of the string is attached to the drive shaft and the other end is connected to a load to form a twisted string actuator (TSA). By controlling the speed and current of the motor, the characteristics of the actuator can be changed. Multiple strings may be located in a flexible soft tube to improve the mechanical properties of the actuator.

A wire rope lubricant having a base fluid as a majority component, and a wax or polymer as a minority component wherein at least one of the base fluid and the wax, or polymer, is biodegradable. A method of forming a wire rope having a plurality of wire strands, the method including the step of applying the wire rope lubricant between the wire strands.

In a musical string (1), in particular for bowed and/or plucked instruments, it is provided that the musical string has a first fluid (6), which is arranged on a first musical string part (2, 4, 5, 9, 10, 11) of the musical string (1), and a second fluid (7), which is arranged on a second musical string part (2, 4, 5, 9, 10, 13) of the musical string (1) and is different from the first fluid (6), wherein the first fluid (6) and the second fluid (7) are arranged to form a first mixing region (15) in at least one first pre-definable oscillating section of the musical string (1).
