We've seen the wireless ECG prototype recently, and now there's yet another wireless device - an EEG to be exact, that draws its power from your body's heat instead. The entire system is wearable and integrated into a headband, consuming a mere 0.8mW of power while its autonomous operation increases the patient's autonomy as well as quality of life. It will utilize IMEC's proprietary ultra-low power biopotential readout ASIC to extract high-quality EEG signals with micro-power consumption. A low-power digital signal processing block will then encode the extracted EEG data, sending it to a computer via a 2.4GHz wireless radio after that. No idea on when this prototype will be commercialized though.
