Abstract: A piezoelectric microelectromechanical structure is provided with a piezoelectric stack having a main extension in a horizontal plane and a variable section in a plane transverse to the horizontal plane. The stack is formed by a bottom-electrode region, a piezoelectric material region arranged on the bottom-electrode region, and a top-electrode region arranged on the piezoelectric material region. The piezoelectric material region has, as a result of the variable section, a first thickness along a vertical axis transverse to the horizontal plane at a first area, and a second thickness along the same vertical axis at a second area. The second thickness is smaller than the first thickness. The structure at the first and second areas can form piezoelectric detector and a piezoelectric actuator, respectively.

Abstract: A modular prosthetic system for an upper limb in which the functional commands of the mechanical limb can be generated by exploiting additional input data with respect to the only muscle contractions of the muscles present on the patient's stump, and the patient can receive a sensory feedback, the richer as possible, regarding to the functionality of the mechanical limb. The modularity of the prosthetic system allows the use of a mechanical artificial limb that essentially implements the pure operational and sensory functions, while the control functions by the patient, and the feedback functions provided to the patient, are managed by a subsystem (called control module) distinct and decoupled from the artificial limb, with which it interacts through appropriate interfaces.

Abstract: A power switch current sensing circuit includes matching first and second transistors having sources connected to first and second terminals, respectively, of the power switch. A current mirror has a first node coupled to a drain of the first transistor and a second node coupled to a drain of the second transistor. The current mirror sinks a current from the first node equal to a current flowing through the second transistor. A biasing circuit provides a same biasing voltage to the control terminals of the first and second transistors. An output resistance is coupled between the first node and a reference voltage node. A difference between a current flowing through the first transistor and the current sunk by the current mirror circuit from the first node flows through the output resistance. An output voltage produced at the first node is indicative of the current flowing through the power switch.
