“…Following this, the torsional actuators driven by interdigitated electrodes (IDEs) have been widely studied [ 22 , 23 ]. Pan proposed a piezoelectric fiber actuator with a small size, with a diameter of 1 mm, and with a pair of HIDEs twisted on the outside surface of the piezoelectric fiber tube [ 24 , 25 ]. Pan also proposed novel discal piezoelectric transducers with spiral IDEs on the surfaces of the piezoelectric disks [ 26 ].…”

This paper presents a novel impact rotary motor based on a piezoelectric tube actuator with helical interdigitated electrodes which has a compact structure and high resolution. The assembled prototype motor has a maximum diameter of 15 mm and a length of 65 mm and works under a saw-shaped driving voltage. The LuGre friction model is adopted to analyze the rotary motion process of the motor in the dynamic simulations. From the experimental tests, the first torsional resonant frequency of the piezoelectric tube is 59.289 kHz with a free boundary condition. A series of experiments about the stepping characteristics of different driving voltages, duty cycles, and working frequencies are carried out by a laser Doppler vibrometer based on a fabricated prototype motor. The experimental results show that the prototype rotary motor can produce a maximum torsional angle of about 0.03° using a driving voltage of 480 Vp-p (peak-to-peak driving voltage) with a duty ratio of 0% under a small friction force of about 0.1 N. The motor can produce a maximum average angle of about 2.55 rad/s and a stall torque of 0.4 mN∙m at 8 kHz using a driving voltage of 640 Vp-p with a duty ratio of 0% under a large friction force of about 3.6 N. The prototype can be driven in forward and backward motion and is working in stick-slip mode at low frequencies and slip-slip mode at high frequencies.

A new torsional piezoelectric vibrating resonator was proposed for measuring the viscosity of Newtonian fluids. It consists of a simple and compact structure as a piezoceramic fiber with parallel helical electrodes around outer surface. Principle of the torsional vibration, theory of the fluid coupling, and methods for the viscosity measurement were presented. A prototype of resonator was fabricated and tested in standard viscosity oils with viscosity × density values from 20 to 1500 Pa·s·kg·m -3 . Experimental results showed a good agreement with theoretical analysis, especially in high viscosity range. With low material and fabrication cost, miniaturized torsional piezoelectric fiber will provide a competitive way for the portable viscosity measurement or in situ monitoring of viscous liquids, such as lubrication oil and fuel in constrained space.

“…The piezoelectric actuator (PA) works as a stator which is excited by a saw-shaped driving voltage to produce periodic asymmetric motion [2,3]. According to the unequal value of driving force and friction force between the contact surfaces of the stator and shaft, the shaft will realize single-direction stepping motion [4]. The impact motor often has a simple structure compared to the inchworm motor and it is often easy to be controlled compared to the ultrasonic motor.…”

A novel impact two-degree-of-freedom (2-DOF) motor based on the decomposed screw-type motion of a piezoelectric actuator (PA) has been proposed. The fabricated prototype motor has a maximum diameter of 15 mm and a length of 100 mm which can produce a maximum torsional angle of about 1000 μrad and a maximum longitudinal displacement of about 1.03 μm under a saw-shaped driving voltage with 720 Vp-p (peak-to-peak driving voltage). When the axial prepressure generated by the spring is about 1N and the radial prepressure generated by the snap ring is about 14 N, the fabricated motor realizes rotary motion with the driving frequency from 200 Hz to 4 kHz. When the axial prepressure generated by the spring is about 11.7 N and the radial prepressure generated by the snap ring is about 21.1 N, the fabricated motor realizes linear motion with the driving frequency from 2 kHz to 11 kHz. In the experiments, the prototype motor can achieve 9.9 × 105 μrad/s rotary velocity at 2 kHz and it can achieve 2.4 mm/s linear velocity at 11 kHz under the driving voltage of 720 Vp-p.
