Micro-robots have wide application prospects on biomedicine, aerospace, etc., and driving technique is critical in researching micro-robot and also the bottleneck in micro-robot development. In this paper, it is proposed that pH gradient generated by electrolysis is used for driving bacteria colonies so as to propel the micro-robot, based on the character of free swimming of flagellar bacterium in...
The kinematics of hand movement have been reported to be encoded in neural activities recorded at the primary motor cortex accompanying or immediately preceding the movement. In our earlier study, we demonstrated that the speed of imagined hand movements can be represented in the noninvasive EEG recordings and continuously decoded. In the present work, we aimed to systematically examine the spectral-temporal...
Many insects like ants can run on the wall or ceiling, due to the micro-force from their special gesture and structure of their limbs. In the paper, we propose a new method of measurement system based on high-speed image detection of revolving target. In the test, we choose ants for our target on the centrifuge, and we can get the maximum adhesive force and friction effectively. As the same time,...
We investigated the source localization performance of the Laplacian weighted minimum norm (LWMN) estimate technique in a realistic geometry (RG) head model in the present study. We simulated current sources at different brain regions with various noise levels. The present results show there is no obvious depth dependency on the three-dimensional (3D) source estimation. The average source localization...
We have developed a new algorithm, FINE, to enhance the spatial resolution and localization accuracy for closely-spaced sources, in the framework of the subspace source localization. Computer simulations were conducted in the present study to evaluate the performance of FINE, as compared with classic subspace source localization algorithms, i.e. MUSIC and RAP-MUSIC, in a realistic geometry head model...
We have developed a high resolution subspace approach for EEG source localization within a realistic geometry inhomogeneous head model. The present study aims to reduce the influence caused by spatially correlated noise from background activities using FINES. Computer simulations were conducted on the realistic geometry head volume conductor model and compared with the classic MUSIC algorithm. The...
We have developed a single trial motor imagery (MI) classification strategy for the brain computer interface (BCI) applications by using time-frequency synthesis approach to accommodate the individual difference, and using the spatial patterns derived from EEG rhythmic components as the feature description. The EEGs are decomposed into a series of frequency bands, and the instantaneous power is represented...
