The advanced progress of electronic-based devices for artificial neural networks and recent trends in neuromorphic engineering are discussed in this review. Recent studies indicate that the memristor and transistor are two types of devices that can be implemented as neuromorphic devices. The electrical switching characteristics and physical mechanism of neuromorphic devices based on metal oxide, metal sulfide, silicon, and carbon materials are broadly covered in this review. Moreover, the switching performance comparison of several materials mentioned above are well highlighted, which would be useful for the further development of memristive devices. Recent progress in synaptic devices and the application of a switching device in the learning process is also discussed in this paper.

Abstrak -Tujuan dari penelitian ini adalah untuk mengembangkan prototype sensor elektromekanik menggunakan polimer konduktif poly (3,4-ethylenedioxythiophene): poly (styrenesulfonate) (PEDOT: PSS). Sebelum melakukan fabrikasi dan karakterisasi sensor, pertama -tama dilakukan verifikasi homogenitas resistansi pada lapisan PEDOT:PSS yang dideposisikan pada substrat isolator. Pada kasus ini, uji homogenitas dilakukan pada 5 posisi berbeda di atas lapisan PEDOT:PSS. Fabrikasi sensor dilakukan pada PEDOT:PSS menggunakan metode drop-coating di atas substrat nitrile rubber. Hasil yang diperoleh pada resistivitas listrik relatif ternormalisasi dari sensor elektromekanik menunjukkan sifat linear terhadap strain sensor. Selain itu, resistivitas sensor dipengaruhi oleh perubahan suhu secara eksponensial pada rentang 30 -80 °C.Abstract -The aim of this research is to develop a prototype of electromechanical sensor by employing conductive polymer poly (3,4-ethylenedioxythiophene): poly (styrenesulfonate) (PEDOT: PSS). Prior to the sensor fabrication and characterization, we first verified the resistance homogeneity of PEDOT:PSS layer deposited on an insulator substrate. In this case, the homogeneity test was performed at five different positions on the PEDOT:PSS layer. The sensor fabrication were carried out by using drop-coating method of PEDOT:PSS solution on nitrile rubber substrats. It is found that normalized relative electrical resistivity of the electromechanical sensor shows linearly to the strain. Moreover, the resistivity of sensor is affected by the change of temperature exponentially in the range of 30 -80 °C.
