“…However, this material cannot always be used effectively due to the high cost of the material [35] and the poor adhesion to the glass substrate. For this reason, a layer of chromium or titanium is additionally deposited before the platinum is deposited to increase its adhesion to the substrate [36][37][38].…”

The paper proposes an innovative method of using microheaters for research on cells in vitro. A method of local heating of a single culture well, compatible with an Electric Cell-substrate Impedance (ECIS) system is presented. A microheater and culture well system for cell culture was modelled. Electrical and thermal simulation of the system under operating conditions was carried out. Correct distribution of heat was observed at the site of the cell culture suspension in the medium, while not affecting the conditions in adjacent wells. As part of the experiment, a heating element of nichrome (NiCr) was created using the magnetron sputtering process. Electrical and thermal measurements of the manufactured device were carried out. It has been shown that it is possible to establish the desired temperature over the long term. In addition, the structures made were characterised by work stability, precision in maintaining the right temperature, and the possibility of being controlled with high accuracy. There is a problem with the precise and reproducible carrying out of a cell culture experiment that differs only in the process temperature. In this work, a technique for increasing the temperature locally, in a single culture well, in a medium containing eight such wells was proposed and analyzed. The use of this method will allow avoidance of the impact of potential changes in parameters other than temperature on the culture. That may occur when comparing cells grown at different temperatures by means of the ECIS (Electric Cell-substrate Impedance) method.

“…The temperature sensor is one of the important carriers of the temperature measurement and control system. It transmits the collected temperature data information to the circuit and directly converts it into electrical signal [10][11][12]. But because the initial signal is relatively small, so you need the influence of the amplification processing of the primary voltage amplification circuit.…”

It changes all year round. In the north, in order to satisfy the public's desire to eat fresh vegetables in winter, vegetable greenhouses came into being. With the rapid development of society, people have put forward higher and higher requirements for the quality of vegetables. The temperature and humidity of the greenhouse have a great influence on the quality of vegetables. Therefore, in order to ensure the quality of vegetables, the temperature and humidity of the greenhouse must be kept within the range most suitable for the growth of vegetables. Therefore, the design of the temperature, room temperature and humidity control system are particularly important. The temperature and humidity control system based on single-chip microcomputer designed in this paper monitors and tempers the greenhouse temperature in real time through the DS18B20 and DHT11 temperature and humidity sensors, respectively, and displays the monitoring results on the liquid crystal display. The single chip microcomputer adjusts the greenhouse temperature and humidity through the monitoring results In order to keep the temperature and humidity of the greenhouse in a constant range. The temperature control system in this paper can achieve a measurement accuracy of ± 0.3 ℃ and a display accuracy of 0.1 ℃. It can also manually adjust the temperature and humidity within a certain range to suit the growth conditions of different vegetables. The results show that the temperature measurement system has the characteristics of high accuracy, high sensitivity, stable operation and so on, which meets the performance requirements of the design. It is a reliable digital temperature measurement control system.

In recent years, the Smart City concept is emerging as a way to increase efficiency, reduce costs, and improve the overall quality of citizen life. The rise of Smart City solutions is encouraged by the increasing availability of Internet of Things (IoT) devices and crowd sensing technologies. This paper presents an IoT Crowd Sensing platform that offers a set of services to citizens by exploiting a network of bicycles as IoT probes. Based on a survey conducted to identify the most interesting bike-enabled services, the SmartBike platform provides: real time remote geo-location of users' bikes, anti-theft service, information about traveled route, and air pollution monitoring. The proposed SmartBike platform is composed of three main components: the SmartBike mobile sensors for data collection installed on the bicycle; the end-user devices implementing the user interface for geo-location and anti-theft; and the SmartBike central servers for storing and processing detected data and providing a web interface for data visualization. The suitability of the platform was evaluated through the implementation of an initial prototype. Results demonstrate that the proposed SmartBike platform is able to provide the stated services, and, in addition, that the accuracy of the acquired air quality measurements is compatible with the one provided by the official environmental monitoring system of the city of Turin. The described platform will be adopted within a project promoted by the city of Turin, that aims at helping people making their mobility behavior more sustainable.
