Summary: This Review Article discusses recent progress in the development of miniaturized and ultralightweight devices for neuroengineering, which are wireless, battery-free, and fully implantable. These devices can restrict natural motions and prevent social interactions in animal models, limiting their utility in behavioural neuroscience research. However, advanced neural interfaces with optical, electrical, or fluidic functionality have emerged, capable of combining recording and stimulation modalities for closed-loop applications in basic studies or the treatment of abnormal physiological processes.

Summary: Battery-free wireless sensor network (BF-WSN) is a new network architecture proposed to solve the lifetime limitation problem of conventional WSNs. BF-WSN can harvest energy from environmental resources or power stations, resulting in an unlimited lifetime in terms of energy. Its specific properties have brought new challenges in energy management, networking, and data acquisition. This survey aims to summarize and analyze the existing algorithms and applications of BF-WSNs.

Summary: The performance of gain switching on a PPM communication system is studied, and it is found that the main factor limiting the data rate is the time delay fluctuation of gain switching. This study demonstrates the use of gain-switched blue GaN-based laser diode in a high-order PPM based UWOC system for the first time.

Summary: This letter introduces a novel antenna structure for 60 GHz band 3-D coverage beamforming, expanding the coverage area in an elevation plane. By packaging dipole and patch subarray antennas together using copper balls interconnection technique, the simple idea of utilizing dipole and patch elements enables endfire and broadside radiations, resulting in the expansion of coverage area in the elevation plane. Two 2 x 4 array antennas are made up of eight multilayered substrates, each with six metal layers.
