Internet of Things: Opportunities and Challenges for Next-Generation Sensor Technology
Assoc. Prof. Dr Asrulnizam Abd Manaf
ABSTRACT: The trend of Internet of Things (IOT) refers to the phenomenon in which not only computers, but all sorts of devices with embedded computing capacity are interconnected. Sensing, processing and connectivity are 3 key points to realize IOT in practical application. Based on report by Yole development at MEMS Engineer Conference 2015 at Tokyo, 4 main sensors will be main contributor for IOT. There are inertial sensor (accelerometer, gyroscope, magnetometer), environmental sensor (pressure, gas, humidity), optical sensor (CMOS,IR) and microphone. However, current sensing technology will have limitation in no standardize for all sensor parameters, power consumption, sensitivity, response time, flexibility, reliability and life span. Thus, need a brilliant innovation in MEMS sensor to support the demand in IOT application especially in issue flexibility and power consumption. In this talk will focus in current development of pressure sensor, flow sensor and incline sensor towards to flexibility of substrate, conductor material and robustness. As pressure sensor application is toward to subtle-pressure regime (1 Pa to 1 kPa) is defined as pressure created by weak interactions of small objects. A sensitive response to such subtle-pressures is necessary for the construction of ultra-sensitive skin-inspired electronic devices that mimic the properties of human skin for potential applications in advanced robotics, prosthetics, and health monitoring. Then, a novel flow sensor and incline sensor sensing technique by implementing of novel fluidic technology with Polymer fabrication technique in realize high robustness of sensor will be introduced. Then, by having a simple structure, high robustness and sensitivity, it can be compatible to integrate with a readout circuitry in realize a next generation sensor for IOT application.
