Nice article by forbes on a question many people forget to ask/challenge. Arguably the greatest hurdles sensor technology for IoT faces right now are system integration and performance over time. Difficulties during this process can occur for a number of reasons.The good news, however, is that sensor technology has proven itself steadfast despite these challenges. For example, sensors must be resilient and strong in the face of harsh conditions. Tech that monitors temperature, fluids and gases, vibrations and sound, or even light can be subject to potential physical damage, leaving a blind spot in the supposed holistic system that IoT entails. But with the advent of powerful sensing materials, particularly various nanomaterials, our sensors are more resilient than ever.
