“…Researchers have studied the rapid and agile locomotion that is commonly performed by different animals, particularly insects, as models for robotic systems [1,[4][5][6][7]. By mimicking the control mechanisms and physical structures of natural biological systems, engineers are able to design mechanical robotic systems to optimize their performance [2,8,9]. Hybrid robotic systems using insects have attracted particular attention in recent years [10,11].…”

“…Hybrid robotic systems using insects have attracted particular attention in recent years [10,11]. The goal of those studies has been to remotely control insects with the purpose of taking advantage of their natural movements [2,8,9,12]. However, establishing efficient control of the natural leg movements of living insects has proven to be a difficult task [10,13,14].…”

Natural systems retain significant advantages over engineered systems in many aspects, including size and versatility. In this research, we develop a hybrid robotic system using American (Periplaneta americana) and discoid (Blaberus discoidalis) cockroaches that uses the natural locomotion and robustness of the insect. A tethered control system was firstly characterized using American cockroaches, wherein implanted electrodes were used to apply an electrical stimulus to the prothoracic ganglia. Using this approach, larger discoid cockroaches were engineered into a remotely controlled hybrid robotic system. Locomotion control was achieved through electrical stimulation of the prothoracic ganglia, via a remotely operated backpack system and implanted electrodes. The backpack consisted of a microcontroller with integrated transceiver protocol, and a rechargeable battery. The hybrid discoid roach was able to walk, and turn in response to an electrical stimulus to its nervous system with high repeatability of 60%.

“…Polyvinylidene fluoride (PVDF) is a piezopolymer, which exhibits sensor and actuator properties. Uniaxially stretched PVDF is used in several sensor applications due to its high sensitivity [1][2][3][4]. Some of the applications such as locomotion sensors, tyre deformation sensors and customized sensors are often subjected to repetitive cyclic loads.…”

Polyvinylidene fluoride (PVDF) is a piezopolymer, and it has numerous applications as sensors and actuators. Uniaxially stretched PVDF subjected to cyclic stresses finds usage in different applications. Characterising the cyclic response of PVDF through appropriate models is important. In this study, we used two approaches to model cyclic stress with the number of cycles. In the first approach, the evolution equations are used and adopted to model the variation of the cyclic mechanical response of PVDF to track the cyclic response at each time step. In the second approach, the effect of cyclic loading on the material, in terms of entropy generation for mechanical and electrical response, is considered for modelling and this approach is adopted to model the PVDF response when subjected to cyclic loading. The mean stress and voltage variation with the number of cycles are predicted.

In this study, we present the results of cyclic electromechanical experiments conducted on uniaxially stretched poly(vinylidene fluoride) (PVDF) films. The experiments were carried out over a range of applied displacement amplitude ranging from 0.5 mm to 1.5 mm, superposed on an initial stretch on the test samples. The strains were calculated using non-contact speckle monitoring method. The hysteresis plots of mechanical and electromechanical cyclic responses are presented. Stress relaxation was observed up to 70% in orthogonal to stretch direction and 16% in the stretch direction. Observed piezoelectricity along both the directions is reported and discussed in the paper.
