One of the main challenges in the field of vibration energy harvesting is to extract energy from the low-frequency ambient vibrations. Since the voltage and power production in vibration energy harvesters depends on the relative velocity (frequency), therefore, comparatively high power levels are produced at a high frequency of vibrations. For low-frequency excitation of the base, technique such as frequency up-conversion (FUC) is widely utilised. In FUC method, a very low-frequency vibration is efficiently harvested using the plucking mechanism. FUC harvesters are comprised of a low-frequency mechanism (primary system) and a high-frequency mechanism (secondary system), which are either coupled operationally through freely moving mass, mechanical plucking, magnetic plucking or mechanical impact. The mechanical contact plucking or magnetic plucking mechanism is used for exciting a secondary system that has a much higher frequency for efficiently harvesting more energy. This work provides a detailed review of the FUC energy harvesters that are utilising freely moving mass, plucking mechanism and mechanical impact techniques reported in the literature. Information about the harvesters' architecture, working, fabrication and output performance is performed with an emphasis on input low frequency, input acceleration, converted high frequency, voltage generation, power levels and power density values reported in the literature. Moreover, all techniques developed for low-frequency vibration applications are compared and the effectiveness of each mechanism used for low-frequency energy harvesting is discussed.

“…Because bioactuators use living tissues, they are distinguished from other actuators by the possibility of a self-repair function that repairs and regenerates damaged tissues to some extent (Raman et al, 2017). Furthermore, they can convert sugar into energy, and in-vivo power generation systems that use skeletal muscle to generate electricity are currently being investigated (Lewandowski et al, 2009;Mochida and Hijikata, 2019;Mochida et al, 2024;Sahara et al, 2016).…”

Bioactuators using skeletal muscle are expected to be applied to medical and welfare equipment as functional materials with self-growth functions. In this regard, their contraction force must be controlled with high accuracy for the desired operation. Therefore, in this study, a model-based control method that follows the contraction force against an arbitrary reference contraction force is proposed to control the contraction of skeletal muscle. The muscle-contraction mechanism is modeled, and the stimulating voltage for exerting the desired contraction force is obtained using this model. Furthermore, the proposed method is validated experimentally using the gastrocnemius muscle of a toad. In the experiment, we identify muscle-contraction model parameters that can reproduce the contraction-force response of the gastrocnemius muscle from experimental data. Using the model, the stimulating voltage for exerting a reference is calculated. The voltage is applied to the gastrocnemius muscle of a toad to control the contraction force. The experimental results show that the proposed model-based control method can control muscle contractions even under a complicated reference contraction force.

“…Micro mobile robots and micro robotic arms (Morimoto et al, 2018;Akiyama et al, 2013) are one of the main examples of biohybrid actuator applications. Skeletal muscles are also distinctive because they convert chemical energy into mechanical energy using sugar as an energy source, and the study on the development of an in vivo power generation system using electrically stimulated muscle is still underway (Lewandowski et al, 2009;Mochida and Hijikata, 2019;Sahara et al, 2016). Since the 2010s, the interest in the field of the biohybrid actuators has been growing rapidly, and the number of published journals has been increasing exponentially (Ricotti et al, 2017).…”

In addition to the characteristics of soft actuators, such as flexibility and elasticity, biohybrid actuators also exhibit few distinctive functions, such as self-growth and self-healing. The previous research on biohybrid actuators has focused on culturing muscle cells and assembling them into micro-robots. These technologies are well-developed, however they lack the design and control methods found in the existing actuators that enable an appropriate performance. Therefore, we propose a simple muscle contraction model against external electrical stimulation, applying the model-based design and realizing the control of biohybrid actuators. The model comprises three sub-models-the electrical dynamic, physiological, and mechanical dynamic characteristics. The input of the model is the time-series stimulation voltage, and therefore, it can be applied to any complex stimulation waveform. The model parameters were identified with multiple square waves with different frequencies and amplitudes, based on the actual skeletal muscle of a toad. Subsequently, in the validation test, the actual muscle contraction was compared with the simulated force that was calculated using the identified parameters. Although the stimulations for the validation were different from those for the identification, the results obtained based on the model showed a good agreement with the experimental results. In addition, the optimal stimulation signal could be also calculated based on the model, to obtain the maximum net work. The findings of this study facilitate the development of model-based design and control methods for biohybrid actuators in the future, that will lead to significant development in this field.
