| Outline of Final Research Achievements |
Thermal sensors for the detection of tiny heat from a single biological cell in a solution have been developed using a microfabrication technique. This sensor utilizes the temperature dependence of the mechanical resonance, and heat transmits to the sensor by thermal conduction via a heat guide. The resonant sensor is thermally isolated from surronding area using vacuum isolation, thus the thermal loss is minimized. Scaling down of the sensor decreases the thermal capasitance of the sensor, which enhance the temperature response. Heat detection from a single cell is demonstrated using the developed thermal sensor.
