Abstract 3D thick electrode design is a promising strategy to increase the energy density of lithium‐ion batteries but faces challenges such as poor rate and limited cycle life. Herein, coassembly method employed construct low‐tortuosity, mechanically robust electrodes. LiFe 0.7 Mn 0.3 PO 4 nanoplates (LFMP NPs) graphene are aligned along growth direction ice crystals during freezing assembled into sandwich frameworks with vertical channels, which prompts fast ion transfer within entire...
Falls are fatal for the elderly, and timely detection after falls is crucial. As a contactless device, radar sensor can monitor users' with advantage of not revealing their privacy. Today, use fall has made significant progress. However, most current methods cannot be used in real complex scenes. They usually collect fewer types actions, ratio number nonfall samples to small, which consistent real-life scene. In addition, classifiers trained tested on same environments people, easily...
This paper presents an energy detection Impulse Radio Ultra-Wideband (IR-UWB) receiver for Frequency Identification (RFID) and Wireless Sensor Networks (WSN) applications. An Application-Specific Integrated Circuit (ASIC) consisting of a 3-5 GHz analog front-end, timing circuit high speed baseband controller is implemented in 90 nm standard CMOS technology. A Field-Programmable Gate Array (FPGA) employed as reconfigurable back-end, enabling adaptive algorithms ranging estimations. The...
In traditional Chinese pulse diagnosis (TCPD), to analyze the health condition of a patient, practitioner should put three fingers on wrist patient adaptively feel fluctuations in radial at styloid processes. Thus, for comprehensive signal acquisition, we efficiently and accurately capture signals different positions under pressures. However, most conventional acquisition devices can only one position fixed pressure, thus limited diagnostic information. this paper, propose our novel solution...
Graphene-based polymer composites with superior electrical and mechanical performance are highly desirable because of their wide range applications. However, due to the mismatch between charge jumping load transfer adjacent graphene sheets, it remains difficult achieve significant, simultaneous improvements in properties graphene–polymer composites. To overcome this issue, we here propose an effective strategy constructed unique 3D conductive networks which compatibility can be improved by...

Increasing interest has been focused on computational pulse diagnosis where sensors are developed to acquire signals, and machine learning techniques exploited analyze health conditions based the acquired signals. By far, a number of have employed for signal acquisition, which can be grouped into three major categories, i.e., pressure, photoelectric, ultrasonic sensors. To guide sensor selection diagnosis, in this paper, we physical meanings sensitivities signals by these types The...
Pulse wave velocity (PWV) measured at a specific artery location is called local PWV, which provides the elastic characteristics of arteries and indicates degree arterial stiffness. However, large cumbersome ultrasound probes require an appropriate sensor position pressure maintenance, introducing usability constraints.
