Solution

The correct option is B Pyroelectric biosensors
The biosensor is a device which can convert a biological response into an electrical response. In pyroelectric sensors, the substances can generate charge due to heat flow. When there is temperature change, the transducer detects the change in the flow of charge and the current is recorded.
Thus, the correct answer is option B.
