this paper proposes an approach for the minimum time swing upof a rotary inverted pendulum. our rotary inverted pendulum is supported bya pivot arm. the pivot arm rotates in a horizontal plane by means of a servomotor. the opposite end of the arm is instrumented with a joint whose axisis along the radial direction of the motor. a pendulum is suspended at thejoint. the task is to design a contro...

This article introduces a soft and stretchable sensor composed of silicone rubber integrating a conductive liquid-filled channel with a biocompatible sodium chloride (NaCl) solution and novel stretchable gold sputtered electrodes to facilitate the biocompatibility of the sensor. By stretching the sensor, the cross section of the channel deforms, thus leading to a change in electrical resistance...

Stretchable RF electronics not only enable applications in which circuits can be wrapped conformally around complex curvilinear shapes or biological tissues, such as in body-worn wireless sensor nodes, [ 1,2 ] and wearable radio frequency...

Rapid growth of stretchable electronics stimulates broad uses in multidisciplinary fields as well as industrial applications. However, existing technologies are unsuitable for implementing versatile applications involving adaptable system design and functions in a cost/time-effective way because of vacuum-conditioned, lithographically-predefined processes. Here, we present a methodology for a f...

Stretchable devices with good transparency offer exciting new applications over the existing technologies, but remarkable difficulties remain in the fabrication of transparent and stretchable devices. In this paper, we report an effective method to fabricate transparent elastic photodetectors which combines the merits of the transparent polydimethylsiloxane (PDMS) polymer with its stretchabilit...

Two-dimensional materials, such as graphene, are attractive for both conventional semiconductor applications and nascent applications in flexible electronics. However, the high tensile strength of graphene results in fracturing at low strain, making it challenging to take advantage of its extraordinary electronic properties in stretchable electronics. To enable excellent strain-dependent perfor...

We investigate several regions of parameter space of a driven pendulum system over which specific phenomena occur. The pivot on which the pendulum hangs is driven in the vertical direction by a periodic force A cos(ωt). We reuse code relevant to the driven pendulum system in SICM: Section 1.6.2 contains the Lagrangian for a driven pendulum in general, Section 1.7 provides for the specific case ...

In order to improve the energy capture efficiency of a multi-pendulum wave energy converter, a mathematical model of the pendulum structure has been built. The final structure parameters of the pendulum have been obtained by using genetic algorithm based on the numerical simulation results of the pendulum structure optimization. The results show that under obtained structure parameters the prop...

Recently, various future devices including microelectronics and bioimplantable devices have been designed as curvilinear layouts on curved or stretchable surfaces of skin or organs. [ 1–4 ] Silicon and polymer-based organics have been used primarily for commercial fl at/rigid electronics and for curvilinear fl exible/stretchable electronics. [ 2 , 5 ] However, 1D materials such as nanowires (NW...
