Engineering nano-clouds that can change color, temperature and outwit heat sensors by Aalto University edited by Gaby Clark, reviewed by Robert Egan Editors' notes ...

Researchers from Aalto University have engineered nanoscale, bio-inspired metasurfaces that act like a real cloud. The nano-clouds can tune colour and temperature — between cooling ...

In this letter, we proposed an ultrasonic sensor-based resolution tunable displacement measurement system by using an extension spring. In the proposed method, a linear extension spring is vertically ...

To address this problem, we propose a ultraprecise simultaneous localization and mapping (SLAM) positioning method, namely, preciseSLAM, which tightly couples LiDAR, inertial measurement unit (IMU), ...

The emergence of triboelectric nanogenerators (TENGs) has significantly developed the landscape of wearable electronics. However, the durability and self-healing capabilities of TENGs remain ...
