It is high time for IR sensor 2.0


The IR sensor is a crucial component in many everyday products, ranging from medical equipment to mobile phones. But the technology is 50 years old and in serious need of an upgrade. In this article, Robert Ekström, CEO of Swedish IR sensor manufacturer JonDeTech, explains that the next generation IR sensor 2.0 for IoT will be much thinner than old sensors and cheaper to manufacture

products or smaller consumer products – they are all more or less dependent on well-functioning sensors that control levels, presence, temperatures and pressures. Even in medical technology, sensors are used, for example, to measure EEG and ECG, to name only two areas of use. The extensive spread of the IR sensor


T


began in the 1950s when industries expanded in size and gained a greater degree of automation. In this process, the sensor came to play a major role in the development of the manufacturing industry, and so it does still today with the same principle. Simply described, the sensor is


required when you need to record and compile the detection and communication of a particular event. And, as mentioned earlier, the applications are numerous. A sensor designed to trigger alarms is often called the detector, and is usually activated when exceeding limit values, such as high temperature or low pressure. Other types of sensors are photodiodes, cameras, microphones, radar, sonar and pressure sensors.


IR SEnSOR 2.0 wIll BE ThE BRIDgE BETwEEn ThE analOguE anD ThE DIgITal In the new connected world that is now emerging, the new IR sensor has the potential to become the bridge between the analogue and the digital world. And the digitally connected world is growing. Therefore, it is not a bold assumption, that in the near future everything that can be linked up will be connected.


32 Security and reliability are of course


impor tant components in such a process, but if there is a demand and customer benefit in place, it will most likely happen. And as stated earlier, the development is very fast. Only ten years ago, there were very few who could predict how many services would move into smar t phones and other consumer electronics. And now there is also a similar development in the area of Internet of Things, where the actual sensors can play an impor tant role.


Small ThERmOpIlE SEnSORS ThaT mEaSuRE hEaT flOw OpEn up fOR nEw aREaS Of uSE The thermopile is a series of series- connected thermo couples that can convert thermal energy into electrical energy. With the help of the new generation of IR sensors, it can also be


used for contactless measurement of temperature and heat flow, as well as presence detection. Thanks to new technology, where the


thermocouple’s lead structure is based on nanotechnology, they are more easily mass produced. The advantage of the vertical arrangement of thermocouple conductors – perpendicular to the plan configuration – is that the hot and cold bonds are separated by the substrate thickness, which is also why the structure becomes more robust compared to the very thin silicon membrane of conventional thermostatic sensors.


ROBuST, pOwER-EffICIEnT, EaSy anD InExpEnSIvE TO pRODuCE The vertical architecture of IR sensor 2.0 makes it possible to manufacture the new sensors out of flexible plastic, instead of fragile ceramics or silicon, which is used in most other IR sensors
