“…Zandrini et al [ 20 ] have utilized the magnetic field to manipulate multiple microrotors (coated successively with amine, Pd and magnetite) with the maximum speed of 600 RPM; Köhler et al [ 23 ] have demonstrated single microrotor assembly with holographic optical tweezer, and a rotation speed of ≈25 RPM was achieved. 2) For microrotor fabricated with UV polymerization, Kaynak et al [ 14 ] have achieved ≈1200 RPM with acoustic actuation of single microrotor at peak‐to‐peak voltage of 160 V and frequency of 4.3 kHz; Moon et al [ 27 ] have adopted the hydrodynamic method to manipulate multiple microrotors and achieved 650 RPM with flow rate of 130 µL min −1 ; Yue et al [ 60 ] have utilized optical laser stimuli to control single microrotor with 60 RPM at a laser power of 2 W. 3) For microrotor fabricated with direct cutting, Loget et al [ 19 ] have adopted the electric field at 0.5 kV m −1 in 50 × 10 −3 m HCl to achieve the single microrotor rotation at the speed of 1 RPM; Jang et al [ 15 ] have combined the teflon tubes together with the laser cutting bodies to generate microrotor, then actuated it with injected bubble acoustic oscillating to achieve a maximum rotation speed of 154 RPM at 2.15 kHz frequency.

“…To produce the mechanical motion of microrotors, it can be generally classified into two categories according to the source of energy: One is driven by an external actuation, such as through acoustic, [ 14–17 ] electric, [ 18,19 ] magnetic, [ 11,20,21 ] optical [ 22–25 ] field, and external forces like hydrodynamic force [ 26,27 ] and bacterial movement. [ 28–30 ] The other type of actuation is relying on the chemical energy [ 19,31 ] conversion within the microfluidic system, which can obtain self‐sustaining energy from the surrounding environment and exhibit microrotor self‐propulsion [ 32,33 ] capability.…”

Simultaneous and uniform actuation of multiple microrotors with easy fabrication method has been gathering significant attention in the field of precise microfluidic manipulation. In this work, the use of a piezoelectric vibration stage is presented to achieve the tunable acoustic vibration‐induced actuation of multiple microrotors fabricated by two‐photon polymerization. A series of curved sharp tips are predefined on the microrotors, which can generate paired asymmetric acoustic microstreaming to propel the rotor rotating around the stator with <1 kHz acoustic vibration. Microrotor's rotational speed can be readily controlled by tuning the signal input frequency and the number of rotor arms. A rotational speed of ≈1600 RPM can be achieved by a series of microrotors in aqueous solutions. This method enables easy and versatile microrotor fabrication and remote actuation of multiple rotors with simplicity and uniformity, providing promising solutions in various microfluidic manipulation applications.

“…With the development of maskless 3-D nanoprinting, more complex and intricate geometries in the propeller designs have been reported [124]. Subsequently, larger prototypes of propellers came into existence with multiple micromachined cavities that offer higher degrees of mobility [106][107][108]. As these large propellers could be driven at kHz frequencies (refer (2.5)), they can be visualized using medical ultrasound (US) systems that operate at MHz frequencies.…”

Contactless acoustic micro/nano manipulation: a paradigm for next generation applications in life sciences

Acoustic actuation techniques offer a promising tool for contactless manipulation of both synthetic and biological micro/nano agents that encompass different length scales. The traditional usage of sound waves has steadily progressed from mid-air manipulation of salt grains to sophisticated techniques that employ nanoparticle flow in microfluidic networks. State-of-the-art in microfabrication and instrumentation have further expanded the outreach of these actuation techniques to autonomous propulsion of micro-agents. In this review article, we provide a universal perspective of the known acoustic micromanipulation technologies in terms of their applications and governing physics. Hereby, we survey these technologies and classify them with regards to passive and active manipulation of agents. These manipulation methods account for both intelligent devices adept at dexterous non-contact handling of micro-agents, and acoustically induced mechanisms for self-propulsion of micro-robots. Moreover, owing to the clinical compliance of ultrasound, we provide future considerations of acoustic manipulation techniques to be fruitfully employed in biological applications that range from label-free drug testing to minimally invasive clinical interventions.

Recent Developments of Acoustic Energy Harvesting: A Review

Acoustic energy is a type of environmental energy source that can be scavenged and converted into electrical energy for small-scale power applications. In general, incident sound power density is low and structural design for acoustic energy harvesting (AEH) is crucial. This review article summarizes the mechanisms of AEH, which include the Helmholtz resonator approach, the quarter-wavelength resonator approach, and the acoustic metamaterial approach. The details of recently proposed AEH devices and mechanisms are carefully reviewed and compared. Because acoustic metamaterials have the advantages of compactness, effectiveness, and flexibility, it is suggested that the emerging metamaterial-based AEH technique is highly suitable for further development. It is demonstrated that the AEH technique will become an essential part of the environmental energy-harvesting research field. As a multidisciplinary research topic, the major challenge is to integrate AEH devices into engineering structures and make composite structures smarter to achieve large-scale AEH.
