The present invention is directed to a wearable system wherein elements of the system, including various sensors adapted to detect biometric and other data and/or to deliver drugs, are positioned proximal to, on the ear or in the ear canal of a person. In embodiments of the invention, elements of the system are positioned on the ear or in the ear canal for extended periods of time. For example, an element of the system may be positioned on the tympanic membrane of a user and left there overnight, for multiple days, months, or years. Because of the position and longevity of the system elements in the ear canal, the present invention has many advantages over prior wearable biometric and drug delivery devices.

A non-invasive wearable sensor device for detecting biomarkers in secretion according to this invention comprises a colorimetric sensor (1), an electrochemical sensor (2), an electrochemical detector and processor (3) and a housing (4). The housing (4) is formed such that allows the colorimetric sensor (1) and electrochemical sensor (2) to contact with the secretion directly and continuously during wearing of the sensor device. This sensor device provides high performance of secretion absorption and retention, leading to high sensitivity to detection of biomarkers using a trace level of secretion sample. This sensor device is developed for detecting biomarkers based on two techniques: the colorimetric sensor (1) which allows the user to interpret a result by comparing it with a standard col or chart, and the electrochemical sensor (2) which provides a digital readout result. This sensor device can be used or simultaneous detection of several biomarkers in the same secretion sample.

An information processor according to an aspect of the present disclosure includes an acquisition section and a generation section. The acquisition section acquires external sweat amount data, on an amount of sweat oozing out of an epidermis, generated on a basis of an output of a first sensor section, and internal sweat amount data, on an amount of sweat inside the epidermis and a dermis, generated on a basis of an output of a second sensor section. The generation section generates sweat amount data on a basis of the external sweat amount data and the internal sweat amount data.
