[1] Department of Electrical and Computer Engineering, The University of the West Indies, St. Augustine Campus, Trinidad and Tobago

Non-communicable diseases (NCDs) have globally become a prevalent problem, accounting for more than 60% of the mortality worldwide. NCDs impose socioeconomic consequences to low-income countries as 80% of NCD deaths occur in such countries [1, 2]. The World Health Organization has ... En savoir plus

Improving the Design Process of a MEMS-IR-Emitter

Toni Schildhauer¹, Andreas T. Winzer¹, Julia Baldauf¹
¹CiS Forschungsinstitut für Mikrosensorik GmbH, Erfurt, Germany

In the rapid development cycle of sensor systems, minimizing time-to-market is crucial. However, designing a new MEMS-chip (Micro-Electro-Mechanical Systems) presents significant challenges due to the extensive time required for manufacturing and characterization. This delay affects the ... En savoir plus

Simulation of DC Current Sensor

RFID-Enabled Temperature Sensor

I.M. Abdel-Motaleb[1], K. Allen [1]
[1]Department of Electrical Engineering, Northern Illinois University, DeKalb, IL, USA

The design of a RFID-enabled temperature sensor is described in this paper. In this sensor, a change in temperature causes structural beams to bend, which results in a proportional displacement of the plates of the capacitor. Plates\' displacement results, in turn, in changing the value ... En savoir plus
