Abstract:

In order to mimic the multifunctional sensing function of skin, a large number of flexible and stretchable sensor arrays have been constructed based on different conduction mechanisms and structural designs. The flexible sensors that can realize multifunctional identification and monitoring of physiological signals related to human health, such as pressure, strain, temperature, humidity and gas, show the great application prospects in the development of wearable artificial intelligence devices. In his paper the latest research achievements in the field of flexible electrochemical sensors with multi-mode monitoring were reviewed. The sensor can detect two stimuli (pressure-strain, pressure/strain-temperature, pressure/strain- humidity, pressure/strain-gas), three stimuli (pressure-strain-temperature, pressure-temperature-humidity, pressure-temperature-gas, etc.) and more than three kinds of stimuli (pressure-strain-temperature-humidity, etc.), which are defined as two-mode sensor, three-mode sensor and multi-mode sensor respectively. This paper focused on the pathway and sensing mechanism of the sensor to achieve multifunctional monitoring. The analysis shows that the methods to achieve multifunctional sensing properties mainly include both structural design and multifunctional material preparation. The flexible multifunctional composites fabricated based on advanced functional materials (including nanometals, nanocarbon and conducting polymers) and flexible matrix materials (such as hydrogels, aerogels and elastic polymers) can effectively reduce the complexity of multi-mode sensors. The characteristics and advantages of different types of functional materials in the fabrication of multifunctional flexible sensors are compared and pointed out to provide implications for the design of multifunctional sensors.

Key words: flexible sensor, wearable device, multifunctional monitoring, electronic material, fabrication
