Similar projects worth following
HealthMon is a ATtiny85/84 based wearable device that allows parents to monitor a sick child's temperature and heart rate remotely via a bluetooth app on the phone.

Strapped to the arm the probes attach to the under arm to provide the inputs. An OLED display allows you to see the current values without having to wake/move the child. Device it battery operated.

Updates are sent from the device via Bluetooth to a connected phone, which will alarm the user if either the temp or the heart rate exceed alert values.

POC device uses an ATtiny85 with an SSD1306 128x64 OLED display.
Temperature probe - TMP36
Heart Rate - piezoelectric sensor

Full version will use an ATtiny84 to allow addition of bluetooth to allow the device to update to a connected device.
