主　　题：electrolyte sensor heating 

摘      要：Heat sensors form an important class of devices that are used across multiple fields and *** applications such as electronic skin and health monitoring,it is particularly advantageous if the output electronic signals are not only high,stable,and reproducible,but also self-generated to minimize power ***,we present an ultrasensitive heat sensing concept that fulfills these criteria while also being compatible with scalable low-cost manufacturing on flexible *** concept resembles a traditional thermocouple,but with separated electrodes bridged by a gel-like electrolyte and with orders of magnitudes higher signals(around 11 mV K^(−1)).The sensor pixels provide stable and reproducible signals upon heating,which,for example,could be used for heat *** modification to plasmonic nanohole metasurface electrodes made the sensors capable of also detecting light-induced ***,we present devices on flexible substrates and show that they can be used to detect human touch.
