Abstract Shape memory polymers (SMPs) undergo changes between arbitrary shapes and programmed shapes upon exposure to specific stimulus, allowing them to restore their original shape. All kinds of external stimuli have a threshold to change the shape

ABSTRACTA gecko foot-inspired, mushroom-shaped artificial dry adhesive exploiting intermolecular forces between microstructure and surface has drawn research attention for its strong adhesive force. However, the high pull-off strength corresponding t

The human fingertip consists of a fingerprint with many micro-grating structures. The main roles of the fingerprint could be divided into two purposes, namely, the enhancement of the frictional force and the effective transmittance of the biosignal.

Gecko feet consist of numerous micro/nano hierarchical hairs and exhibit a high adhesion onto various surfaces by van der Waals forces. The gecko, despite its mighty adhesion, can travel efficiently with a rapid adhesion switching due to the end of t

In this paper, we consider channel estimation with the use of dedicated pilot signal in multiple-input multiple-output orthogonal frequency division multiplexing wireless systems. The dedicated pilot signal is transmitted through a channel virtually
