在处理器性能与无线通信技术日新月异的情况下,物联网有望在未来几年快速走进我们的生活。微控制器(MCU)作为物联网的核心零组件,无论在市场规模上还是技术上都将获得进一步发展。
MCU+无线快速成长
物联网的宗旨是万物皆可联网,借以构成庞大的应用系统,并打造智慧的生活环境。因此,物联网设备势必需要具备联网能力,同时还要兼顾成本和功耗。这一需求促使无线微控制器解决方案势力抬头。众多MCU大厂都注意到这一趋势,开始整合蓝牙、WiFi…
现在智能穿戴设备非常的火爆,不过产品大多还是智能手表、手环、眼镜一类。不过日前博通在深圳举办的一次媒体见面会上,博通公司中国区高级销售总监钱志军展示了一件可穿戴智能运动T恤。
这件衣服是AiQ公司和博通合作的可穿戴运动T恤,可以测量心率、ECG等多个信号,据称为了测量准确——比如臂围要正好合适以便准确测量心率,这套衣服是专门量身制作的。(备注:AiQ公司是一家服装面料厂商,耐克、阿迪达斯等都有采用其运动服装面料)
衣服手臂位置装有传感器,接上纽扣状的无线发射器,运动时所测量的信号就可以通过博通的WICED平台可以传送到云端…
