background

● Cheap and easy-to-use chemical sensors are required for health care based on medicine.  
● Long time sticking to the skin sometimes produce a rash and a sense of incongruity. (Fig.1)
● Users feel trouble for regular wearing with a battery and the wiring.

summary

● Sticking a tiny sensor module on the skin using a polymer nanosheet. (Fig.2(a)) 
● Silicon pH (ion) sensor suitable for a mass production and ultra small reference electrode. (Fig.2(b)) 
● The sensors are driven without a battery directly by near-field communication (NFC). (Fig.2(c)) 

predominance

● Biocompatible nanosheet is kind to he skin and no incongruity during wearing.
● The module is comprised of the low-cost part of the silicon base.
● Simple operation by sensor drive and the data analysis with the smartphone.

application/development

● Monitor of skin pH and sweat ion for health and sports.
● Management of meat (pH of the maturational meat) and animals. (Fig.3)
● Detection of stress markers from sweat (as future technology: Fig.4).
