As one emerging bionic technique, the swarm robotics is a coordination and control strategy of multiple-robot systems, where a number of relatively simple robots are effectively integrated to complete sophisticated tasks while possessing characteristics of high robustness, flexibility, and low cost. Alike other electrified devices, however, the energy storage is an inevitable technique issue impeding...
A narrow-size planar monopole antenna for triple-band operation is presented. The proposed antenna consists of a half E-shaped metal patch, a 50 ohm coplanar waveguide (CPW) transmission line and a branch extended from the ground. The narrowness of the antenna is achieved by applying the asymmetric coplanar strip (ACS) structure to the prototype one. The multiband characteristic of the antenna is...
Low power and small volume are always the most important issues in the internal module of a wireless implantable neural recording system. In this paper, a BPSK demodulator base on digital-analog hybrid COSTAS Loop is presented. A digital multiplier replacing the analog multiplier is presented specially to achieve lower power consumption in the proposed circuit. The proposed BPSK demodulator features...
Wireless Sensor Network (WSN) is a network whose energy is constrained. To efficiently use energy and enhance network viability is one of the main objectives for designing WSN. Some new concepts about the vitality of WSN are proposed, and a vitality evaluation method for WSN is studied in this paper. The analysis showed that the vitality evaluation method proposed is effective and useful.
Low power, small volume and high acquisition precision are always important in the internal module of wireless implantable neural recording system. This paper describes the design and implementation of a new successive approximation (SAR) ADC to meet the unique requirements of wireless implantable neural recording system. In the designed new ADC, a fully differential structure is used to avoid the...
Research shows that low power is always needed in the internal module of a wireless implantable neural recording system. In this paper, a clock multiplier with very simple circuit structure was presented. Using this clock multiplier to replace the analog multiplier in the traditional BPSK demodulator, a new BPSK demodulator with simpler circuit structure and hence lower power consumption can be obtained...
