From the head researcher (John Rogers at the University of Illinois at Urbana-Champaign) who brought you biodegradable implanted batteries and sensors [TTA 26 March], comes an almost tattoo-like stretchable sensor conforming to the skin which uses off-the-shelf, chip-based electronics for wireless monitoring. It is envisioned for wireless health tracking connecting to smartphones and computers, and for vital monitoring such as ECG and EEG testing, although this Editor would not use the term ‘clinical’ as Gizmodo has done (it is probably at the fairly sound level of an AliveCor.) However the article points out the advantages in long term use–adherence to skin is far more reliable, no dangling pendants or clunky bracelets, and it allows for multiple sensors to be worn comfortably. This type of patch would also be far kinder to the delicate skin of babies and the elderly. For them, it would make consistent long-term telehealth monitoring (e.g. blood pressure, ECG, O2, blood glucose) far easier over time. Perhaps the core of this is the PERS of the future with gait tracking and fall detection. Cost isn’t mentioned, but off the shelf elements undoubtedly are less expensive than custom/bespoke.
