中国徐州网-彭城晚报讯(记者 魏欣) 5月3-4日,由团市委主办的2017徐州青年创新创业项目对接会在蜂巢众创空间举办。本次活动为了鼓励青年人做成自己的事业,实现自己的梦想,以科“创”青春,智“汇”未来为主题,有轨电车、机器人、植保无人机、古建筑3D打印等科技创新成果集中亮相,一大波徐州的有志青年聚集在这里,向世人展示他们的创新创业成果。

相比传统假肢,3D打印假肢价格低廉、质量轻

在青年科技创新项目“智能工坊”展示区,记者注意到,一款“3D打印假肢”项目格外引人注目。据悉,这是由徐州医科大学五名年龄在20岁左右的大学生研发出来的。项目研发团负责人告诉记者,他们研制的“3D打印假肢”相对于传统假肢,价格低廉、质量轻、佩戴方便。主要是针对手掌、手臂的截肢患者用的,尤其对于正处于成长期的儿童和青少年患者,要频繁更换假肢,而3D打印假肢将更节约时间与成本,对零件或某一部位的损坏,无需整套更换,根据损坏部位,对零件单独进行打印,最后重新安装即可。 目前,这种3D打印假肢基本实现生活中所具备的基本抓、握、拿等功能,且耐磨,不容易损坏。

安全救援机器人可赴险地取物

由江苏安全技术职业学院一支15人的学生团队研制出的“安全救援机器人”能够完成深赴火灾、毒气、爆炸或是狭小空间等危险的境地,完成放、取物品的任务。记者在现场看到,这款机器人长80厘米、宽40厘米左右,机器人伸着长长的臂膀,灵活自如,上、下、左、右全方位伸展、按指令抓取物品。而且这款机器人已经实现了手机遥控端,操控者只需要在手机上操作,即可模拟排爆过程、救援等操作。

另外,这个团队还研发了一款智能语音机器人:该机器人利用云服务技术,不仅可以实现智能对话,能够完成一定的动作演示,能够按指令进行运动行走,并且能够与人进行点单问答交流,最吸引人眼球的是,这款机器人还能实现表情化,它可以通过自己的眼球变化,来表达自己的喜怒哀乐。高兴时,它的眼球会呈月芽状、生气时,他会怒目圆睁,眼球呈圆环状,遇到自己喜欢的东西时,他的眼球就变成了“心”形,代表倾慕已久。

防雾霾纱窗不止防雾霾,还隔水、隔冷热

在对接会生态E家展区,一款防雾霾纱窗让不少观众驻足许久。为了防雾霾,市民们不断地购买空气净化器以保证室内空气的洁净。如果能有一款防雾霾的纱窗,把雾霾远远地隔在窗口外,岂不更好?记者在现场看到,在一个三面玻璃的盒子里,使用普通窗纱PM2.5值是58,采用这款防雾霾窗纱PM2.5很快就下降到了28,据这款项目的研发人介绍,这个数值会继续下降,一直到接近零。这位负责人说,这款防雾霾纱窗使用独创的“高分子微孔过滤技术”和过滤材料,能够有效吸附空气中的细菌、微尘等物质,并释放天然负氧离子。正常情况,室外雾霾指数在300左右时,装上蓝冠防雾霾纱窗,能保证室内雾霾指数在80以下。

记者注意到,这款窗纱的神奇之处在于不止防雾霾,还隔水,隔冷热,同时透气性又非常好。这意味着如果安装了这款窗纱,房子里开了空调或者暖气也可以开着窗子透气。

除了这款防雾霾纱窗,另一款智能新风净化项目也受到许多观众的青睐。这款新风净化系统是一种将室外空气经过过滤、净化,热交换处理后送进室内,同时又将室内受污染的有害气体经过热交换处理后排出室外,清洁净化室内空气,提高含氧量,同时不影响室内温度的一种高效节能、环保型的高科技产品。产品还结合了物联网大数据处理技术开发了智能环境监控系统,通过手机或者PC端就可以远程实时掌握当前空气质量状况。

在这次青年创新创业项目对接会上,“中国古建筑和3D打印的有机结合”“全国领先大成植保无人机”“污染源水质在线监测系统”“智能家居”等一些节能、节地、环保、便捷的创新项目最受观众关注,也将成为青年们不断创新、研发的新目标。
