I can’t tell you how many tubes of Clinique’s Black Honey Pop Lip & Cheek Stain I’ve been through. Let’s assume dozens. And now that it’s also available in Nude Honey, well, add a few more oils to my ...

Abstract: Low-power wireless stand-alone sensors that can operate without any wiring have received significant attention in sensor network applications. These devices harvest environmental energy ...

Sensors are found in a wide variety of devices ranging from cell phones (there are as many as 14 in a smartphone—from accelerometers and gyroscopes to front- and rear-mounted image sensing cameras) to ...
