MIT 'radio' uses wireless signals to identify emotions

You can lie to your partner, your best friends and even your mom, but you can't lie to EQ-Radio. It's a device out of MIT"s Computer Science and Artificial Intelligence Lab (CSAIL) that can tell how you truly feel by bouncing wireless signals off your body. Yep, you don't need to be connected to the device with ECG patches and wires. EQ-Radio has algorithms that can extract your heartbeat from the signals your body reflects. It then analyzes each heartbeat and compares it to your previous measurements. According to the team, the device is 87 percent accurate with your measurements on file, but it's still up to 70 percent accurate without them.
