The thermodynamic method applied to hydraulic transmissions
Proceedings of the JFPS International Symposium on Fluid Power, 1993 Two hydraulic transmissions are tested for determination of the efficiency by two methods, the basic one by hydraulic measurements and the other by thermodynamic measurements. The hydraulic method is giving the total efficiency of the transmission on the base of hydraulic power input to the motor and hydraulic power output from the pump.

An integrated compact digital hydraulic converter prototype for hydraulic transmission [PDF]
Digital hydraulic converters are innovative devices that enable efficient regulation and control of hydraulic fluid flow and pressure. Unlike conventional methods that employ flow throttling and power dissipation, digital hydraulic converters use digital control signals to create highly efficient hydraulic fluid power systems.

Modeling and Characterization of a Self‐Sensing Soft Hydraulic Muscle
Advanced Intelligent Systems, EarlyView.This article presents the self‐sensing soft hydraulic muscle (SSHM), a novel soft actuator capable of simultaneously sensing force and length without external sensors. A comprehensive model accurately predicts SSHM behavior, validated experimentally with minimal errors. Using propylene glycol enhances durability and reduces hysteresis.
