A Novel On-Chip Impedance Sensor for the Detection of Particle Contamination in Hydraulic Oil

Micromachines, 2017
A novel impedance sensor based on a microfluidic chip is presented. The sensor consists of two single-layer coils and a straight micro-channel, and can detect, not only ferromagnetic and non-ferromagnetic particles in oil as an inductive sensor, but also,

Sistem Telemonitoring KWH Meter Menggunakan Modul Wi-Fi ESP8266 Berbasis Arduino Uno

Jurnal Rekayasa Elektrika, 2019
The postpaid KWH Meter reading by officers is sometimes constrained to reach the physical KWH Meter because the house fence is locked or the KWH Meter is inside the house. This often causes problems such as reading errors and the officer must come to the

Photonic porous silicon as a pH sensor [PDF]

, 2014
Chronic wounds do not heal within 3 months, and during the lengthy healing process, the wound is invariably exposed to bacteria, which can colonize the wound bed and form biofilms. This alters the wound metabolism and brings about a change of pH. In this
