“…Perkembangan IoT dapat dilihat mulai dari tingkat konvergensi teknologi nirkabel, microelectromechanical (MEMS), internet, dan QR (Quick Responses) Code [4]. IoT juga sering diidentifikasi dengan [5] RFID (Radio Frequency Identification) sebagai metode komunikasi [6]. Pada perkembangannya internet of things banyak memodernisasi peralatan-peralatan elektronik yang masih memiliki sistem konvensional dirubahnya menjadi sistem yang ditanam [7] suatu program dengan algoritma tertentu untuk dapat dikendalikan, dipantau, atau dipantau dari jarak jauh [8].…”

Graphic User Interface (GUI) pada suatu sistem Internet of Things (IoT) salah satunya dipengaruhi oleh monitor yang mudah diakses, fleksibel, serta efisien dalam penggunaannya. Hal ini sudah banyak didiskusikan namun masalah tersebut masih belum dapat ditingkatkan. Salah satu solusi dari masalah tersebut adalah dengan dihadirkannya MQTT Adafruit, yang mana dengan menggunakan MQTT Adafruit GUI untuk memonitor suatu sistem IoT dapat mempermudah kontrol dan kendali jarak jauh. Penelitian ini bertujuan untuk menghadirkan sistem monitoring beban listrik dan perbaikan faktor daya menggunakan PZEM004T berbasis IoT yang sudah menggunakan MQTT Adafruit sebagai user interface-nya. Metode yang digunakan melalui pendekatan analysis, design, development, implementation, evaluation (ADDIE). Hasil penelitian menunjukan bahwa sistem ini layak digunakan karena berdasarkan hasil percobaan faktor daya yang sebelumnya 0,35 menjadi 0,89 setelah dilakukan perbaikan faktor daya. Sistem ini juga memberikan kemudahan bagi pengguna dan dapat melakukan monitoring secara real time arus, tegangan, faktor daya, daya nyata, daya semu, dan daya reaktif baik hanya dengan menggunakan smartphone, laptop, tablet, maupun komputer. Berdasarkan hasil uji reliabilitas alat ini memiliki selisih yang kecil antara setiap hasil percobaan.

In this study, we present a comprehensive review of polymer-based microelectromechanical systems (MEMS) electromagnetic (EM) actuators and their implementation in the biomedical engineering field. The purpose of this review is to provide a comprehensive summary on the latest development of electromagnetically driven microactuators for biomedical application that is focused on the movable structure development made of polymers. The discussion does not only focus on the polymeric material part itself, but also covers the basic mechanism of the mechanical actuation, the state of the art of the membrane development and its application. In this review, a clear description about the scheme used to drive the micro-actuators, the concept of mechanical deformation of the movable magnetic membrane and its interaction with actuator system are described in detail. Some comparisons are made to scrutinize the advantages and disadvantages of electromagnetic MEMS actuator performance. The previous studies and explanations on the technology used to fabricate the polymer-based membrane component of the electromagnetically driven microactuators system are presented. The study on the materials and the synthesis method implemented during the fabrication process for the development of the actuators are also briefly described in this review. Furthermore, potential applications of polymer-based MEMS EM actuators in the biomedical field are also described. It is concluded that much progress has been made in the material development of the actuator. The technology trend has moved from the use of bulk magnetic material to using magnetic polymer composites. The future benefits of these compact flexible material employments will offer a wide range of potential implementation of polymer composites in wearable and portable biomedical device applications.

Out-of-Plane Soft Lithography for Soft Pneumatic Microactuator Arrays

et al. 2023

Elastic pneumatic actuators are fuelling new devices and applications in soft robotics. Actuator miniaturisation is critical to enable soft microsystems for applications in microfluidics and micromanipulation. This work proposes a fabrication technique to make out-of-plane bending microactuators entirely by soft lithography. The only bonding step required is to seal the embedded fluidic channels, assuring the structural integrity of the microactuators. The process consists of fabricating two SU8 mold halves using different lithographic layers.Polydimethilsiloxane (PDMS) is poured on the bottom mold, which is subsequently aligned and assembled with the top mould. The process allows for out-of-plane actuators with a diameter of 300 µm and for fabricating arrays of up to 36 actuators that are row-addressable.These active micropillars have an aspect ratio of 1:1.5 and when pressurized at 1 bar, show a bending angle of approximately 30°.
