Body Area Network: Temperature and Heart Rate monitor

Body Area Network: Temperature and Heart Rate monitor I need a sensor to detect someone's pulse and temperature. Ideally from fingertip or wrist. This will then need to transmit the data using an analogue sensor to sample the data at an appropriate rate via Bluetooth to a raspberry pi which will display the information on a TV via hdmi. The sensor needs to be low cost/ small and low power. Can be powered using a coin cell battery or somekind of flex battery. Open to options. The data collected by the sensor needs to be either streamed over Bluetooth to the raspberry pi or stored on board the sensor until ready to transmit. I will need someone to design the PCB and create the schematic for me to build. Also the coding to read the data and send to the raspberry pi to display the information. Any information used to design the schematic (maths/ caluclations etc) will be needed too. Timeline: Ideally the pcb should be done soon. Ideally within a week or two. The coding can be finished later. Ideally in December.
