基于无线自供能的植入式微纳集成芯片与集成系统

我国是慢性病大国,癌症、糖尿病、心脏病、癫痫、高血压等疾病已成为首要致死原因,医疗负担占比70%,形势严峻.相比口服,注射等传统给药方式,植入式精准靶向治疗按时按需、精准适量,见效迅速,几乎无副作用,被证实是慢性病的有效治疗方式.目前我国在这一领域刚刚起步,尤其在高端植入微纳集成系统级芯片(System of Chip,SoC)、微纳系统集成和封装可靠性等方面,缺少原创性核心技术和共性技术支撑平台,严重落后于欧美发达国家,相关高端医疗器械及核心部件只能高价进口.因此,需要通过突破相关关键共性技术,核心部件国产化,从创新源头推动高端医疗器械发展,从而加速推动我国医疗器械产业化落地,打破欧美日发达国家垄断.本研究以突破医疗用微纳集成芯片和微纳集成系统关键共性技术为目的,解决了微电子小尺寸、高精度、低功耗等难题.通过三维异质集成构建植入式精准靶向给药系统和迷走神经刺激器,实现精准靶向给药、无线充电、生物电信号采集、电刺激等功能,项目样机已通过生物相容性测试和动物实验验证.     

综艺节目中全息投影技术的应用

半导体封装中的可视化技术

树脂传递模封装是广泛使用的可靠性量产性均好的半导体封装方法。但随着封装体（PACKAGE）尺寸的日益薄型化和多腿化,不可避免地会发生与树脂在模腔中流动状态有关的空隙等使制品失效的不良模式。这样,通过观察树脂流动状态及对空隙的分布进行研究,对于研究空隙发生机理从而抑制空隙发生具有重要意义。本文将着重介绍两种新的研究实验方法：（1）应用玻璃嵌入式新型可视化模具观察树脂在模腔中的流动状态;（2）采用超声波探查图像装置（简称SAT）进行树脂封装体内部的观察。

Novel Rotating Hairy Black Hole in （2 ＋ 1） Dimensions

We present some novel rotating hairy black hole metric in （2 ＋ 1） dimensions, which is an exact solution to the field equations of the Einstein-scalar-AdS theory with a non-minimal coupling. The scalar potential is determined by the metric ansatz and consistency of the field equations and cannot be prescribed arbitrarily. In the simplified, critical ease, the scalar potential contains two independent constant parameters, which are respectively related to the mass and angular momentum of the black hole in a particular way. As long as the angular momentum does not vanish, the metric can have zero, one or two horizons. The case with no horizon is physically uninteresting because of the curvature singularity lying at the origin. We identify the necessary conditions for at least one horizon to be present in the solution, which imposes some bound on the mass-angular momentum ratio. For some particular choice of pararneters our solution degenerates into some previously known black hole solutions.     

Confronting the DAMPE excess with the scotogenic type-Ⅱ seesaw model

The DArk Matter Particle Explorer(DAMPE) has observed a tentative peak at E ~ 1.4 Te V in the cosmic-ray electron spectrum.In this paper,we interpret this excess in the scotogenic type-Ⅱ seesaw model.This model extends the canonical type-Ⅱ seesaw model with dark matter(DM) candidates and a loop-induced vacuum expectation value of the triplet scalars,v?,resulting in small neutrino masses naturally even for Te V scale triplet scalars.Assuming a nearby DM subhalo,the DAMPE excess can be explained by DM annihilating into a pair of triplet scalars which subsequently decay to charged lepton final states.Spectrum fitting of the DAMPE excess indicates it potentially favors the inverted neutrino mass hierarchy.We also discuss how to evade associated neutrino flux in our model.     

Probing light DM via the Migdal effect with spherical proportional counter

Owing to its low electronic noise and flexible target materials, the Spherical Proportional Counter(SPC)with a single electron detection threshold can be utilized to search for sub-GeV dark matter(DM). In this study, we investigate the prospects for light DM direct detection via the DM-nucleus Migdal effect in the DARKSPHERE detector. We consider different DM velocity distributions and momentum-transfer effects. For Xenon and Neon targets, we find that the DM mass mDM can be probed down to as lo...
