This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...
What is a SWED? How the research team's SWED design significantly improved imaging. Initial test results with the SWED design. The standard two-dimensional array of piezoelectric sensors used for ...
Flexible piezoelectric sensors are essential to monitor the motions of both humans and humanoid robots. However, existing designs are either are costly or have limited sensitivity. In a recent study, ...
This open-circuit voltage data combined with the figure for the power management unit's start-up voltage reveals whether the piezo will power-up the wireless sensor node. As an example, consider the ...
