“…However, it increases the size of the device, and the fabrication process is much more complex. In addition, the materials commonly used for Hall sensors are greatly influenced by temperature [ 83 ], which limits the application of Hall tactile sensors in complex environments.…”

In the past two decades, biomimetic tactile sensing technology has been a hot spot in academia. It has prospective applications in many fields such as medical treatment, health monitoring, robot tactile feedback, and human–machine interaction. With the rapid development of magnetic sensors, biomimetic tactile sensing technology based on magnetic sensors (which are called magnetic tactile sensors below) has been widely studied in recent years. In order to clarify the development status and application characteristics of magnetic tactile sensors, this paper firstly reviews the magnetic tactile sensors from three aspects: the types of magnetic sensors, the sources of magnetic field, and the structures of sensitive bodies used in magnetic tactile sensors. Secondly, the development of magnetic tactile sensors in four applications of robot precision grasping, texture characterization, flow velocity measurement, and medical treatment is introduced in detail. Finally, this paper analyzes technical difficulties and proposes prospective research directions for magnetic tactile sensors.

“…Salah satu ukuran sensor dikatakan baik dapat dilihat dari nilai kelinearannya (Liu et al, 2019). Jika respon sensor linier, sensitivitas akan tetap konstan sesuai dengan rentang sensor dan sama dengan tingkat kemiringan grafik (Mo et al, 2021). Namun, jika respon sensor tidak linier, sensitivitasnya akan bervariasi sesuai dengan rentang sensor (Liu et al, 2020).…”

Di masyarakat, termometer yang biasa digunakan untuk mengukur suhu berbasis air raksa atau alkohol. Namun, ada beberapa kelemahan termometer air raksa atau alkohol. Termometer alkohol memiliki kelemahan yaitu dinding kaca menjadi sedikit basah, sulit membaca suhu yang diukur, dan alkohol tidak berwarna. Oleh kerena itu dibuat termometer sederhana yang memiliki keunggulan seperti pembacaan suhu yang lebih teliti, lebih aman digunakan dan bahan-bahan dalam pembuatan termometer lebih sederhana. Penelitian ini dilakukan dengan cara memvariasikan setiap lilitan kawat untuk melihat perubahan yang terjadi. Data yang diperoleh dari penelitian di Logger pro dalam bentuk grafik dan nilai yang terukur. Setalah data diperoleh data di pindahkan ke MS excel yaitu nilai t waktu, nilai dari T suhu dan I Intensitas. Hasilnya Rentang suhu yang paling baik untuk melihat kemiringan kurva adalah pada suhu 38 -100 ºC. Pada saat rentang suhu tersebut terjadi perubahan nilai yang cukup baik sehingga bisa diperoleh nilai konsistensi yang paling baik adalah pada kawat dengan 150 lilitan, nilai R 2 = 0,99 dengan persamaan y = -5.5246x + 4174,5.

“…17,18 Hall sensor is small and has fast response speed but has low sensitivity. [19][20][21][22] AMR has the advantages of noncontact operation, easy maintenance, and robustness to contamination 23,24 and they are much more sensitive than any semiconductor sensor, 25 which is usually used to measure MFD of 0.2 mT to 2.5 mT. SQUID uses the principle of Josephson effect to measure the magnetic eld.…”
