“…With a higher frequency, US imaging gives a better axial resolution, yet the imaging depth will be relatively shallow since highfrequency US waves are easier to be attenuated. The imaging contrast is related to the acoustic resistance difference between the target microrobot and the surrounding environment, thus by increasing the acoustic resistance of the microrobot (e.g., air Electrohydrodynamic [216,217] Acoustic Actuation Bulk Wave [218,219] Surface Wave [220][221][222][223][224][225] Traveling Wave [226,227] Light Actuation Photophoresis [228][229][230][231] Optomechanical Response [32,232,233] Optical Tweezer [234][235][236] Magnetic Actuation Magnetic Gradient Force [121,[237][238][239][240] Magnetic Torque [19,35,64,98,241,242] Multi-stimuli Actuation [36,243,244] Table 2.

“…To date, various methods have been proposed to actuate microrobots, such as bio-hybrid actuation, chemical fuel, electrical field, light, acoustic wave, and magnetic field. [29][30][31][32][33][34][35] Furthermore, multiple stimuli can be employed simultaneously to achieve actuation and precise navigation of microrobots. [36] By adjusting the control inputs of the external stimuli, parameters like speed, moving direction, and geometric shape of the robot can be tuned accordingly.…”

After decades of development, microrobots have exhibited great application potential in the biomedical field, such as minimally invasive surgery, drug delivery, and bio‐sensing. Compared with conventional medical robotic systems, microrobots may be capable of reaching more narrow and vulnerable regions in the human body with minimal damage. However, limited by the small scale of microrobots, microprocessors, power supplies, and sensors can hardly be integrated on‐board. Thus, new strategies for the actuation and feedback for microrobots need to be explored. Furthermore, the open‐loop control method accomplished by operators may lack accuracy, and long‐duration operation could bring a severe physical challenge in many applications. Consequently, the automatic control of microrobots with the aid of control theories is developed to improve the control efficiency and precision. To further promote the automation level of microrobots, machine learning algorithms are expected to provide a solution to let microrobots adapt to more dynamic environments and undertake more complex medical tasks. Herein, a systematic introduction of the manipulation of microrobots from open‐loop to closed‐loop control is given in this review. It is envisioned that microrobots will play an important role in future biomedical applications.

Passive symmetry breaking of the space-time propagation in cavity dissipative solitons

Dissipative solitons are fundamental wave-pulses that preserve their form in the presence of periodic loss and gain. The canonical realization of dissipative solitons is Kerr-lens mode locking (KLM) in lasers, which delicately balance nonlinear and linear propagation in both time and space to generate ultrashort optical pulses. This linear-nonlinear balance dictates a unique pulse energy, which cannot be increased (say by elevated pumping), indicating that excess energy is expected to be radiated in the form of dispersive or diffractive waves. Here we show that KLM lasers can overcome this expectation. Specifically, by breaking the spatial symmetry between the forward and backward halves of the round-trip in a linear cavity, the laser can modify the soliton in space to incorporate the excess energy. Increasing the pump power leads therefore to a different soliton solution, rather than to dispersive / diffractive loss. We predict the symmetry breaking by a complete numerical simulation of the spatio-temporal dynamics in the cavity, and confirm it experimentally in a KLM Ti:Sapphire laser with quantitative agreement to the simulation. The simulation opens a window to directly observe the nonlinear space-time dynamics that molds the soliton pulse, and possibly to optimize it.

“…On the dynamic property side, accurate characterization of vibrations and dynamic behaviours in microand nano-mechanical devices is critical for understanding the underlying physics and advancing their applications. In particular, recent emergence of various nonlinear, transient, and complex mechanical dynamics, such as anharmonic vibrations in micro-and nano-mechanical resonators [17][18][19][20] , pulsed optomechanics 21,22 , phononic frequency combs 23 , ultrasound sensors 24 , and optomechanical solitons 25 , to name a few, has necessitated real-time surface deformation imaging with ner axial and lateral resolutions, higher speed, and higher dynamic range. Coherent interferometers and white-light interferometers have been widely utilized due to their nanometric axial resolutions and reliability, however, they suffer from sub-micrometre ambiguity range 11,13 and slow (few-Hz) video rate 26 , missing motions faster than ~ metre-per-second.…”

High-speed and high-resolution imaging of surface profiles is critical for the investigation of various structures and mechanical dynamics of micro- and nano-scale devices. In particular, recent emergence of various nonlinear, transient and complex mechanical dynamics, such as anharmonic vibrations in mechanical resonators, has necessitated real-time surface deformation imaging with higher axial and lateral resolutions, speed, and dynamic range. However, real-time capturing of fast and complex mechanical dynamics has been challenging, and direct time-domain imaging of displacements and mechanical motions has been a missing element in studying full-field structural and dynamic behaviours. Here, by exploiting the electro-optic sampling with a frequency comb, we demonstrate a line-scan time-of-flight (TOF) camera that can simultaneously measure the TOF changes of more than 1000 spatial coordinates with hundreds megapixels/s pixel-rate and sub-nanometre axial resolution over several millimetres field-of-view. This unique combination of performances enables fast and precise imaging of both complex structures and dynamics in three-dimensional devices and mechanical resonators.
