【Abstract】 In 1981 Department of Physiology, Shinshu University School of Medicine and Nagano National College of Technology jointly started to develop perspiration meter using moisture sensor. Based on the approved patent Suzuken Co., Ltd. started to make a practical unit. It has received the approval as a useful medical unit for hyperhidrosis and anhidrotic diagnosing in 1991. Mr. Nakamura developed a perspiration meter based on reference difference method in 1998 and started a university venture company called Skinos in September 1998. Both Prof. Ohhashi and Prof. Sakaguchi became the executive of Skinos. Sell perspiration meters to medical and research field and private enterprises.

## [Summary of the technology transfer]

## Technological Impact

• air flow capsule perspiration meter based on measuring environment ambient air as reference : measure moisture before capsule and after capsule with two different moisture sensors and from the difference estimate perspiration amount.

• small and easy to use

• output sensitivity is 0.01mg/cm² · min

• equipped with perspiration analytical software

## Market Impact

Convenience of taking the unit anywhere made the unit as evaluating device in the field of medical research, medical practice and sensitivity research such as physical exercise, cosmetics, clothing, and bed clothing, comfort in car seat.

## ●Social Impact

Perspiration research is a Japanese proud medical research area. In August 1998, the Japanese Society for Perspiration Research (President; Prof. Ohhashi) was established based from the mental perspiration research group in order to contribute perspiration research development and apply in practice.

●Special Features of the Collaboration

To participate JS for PR activity and develop devices based on the member's needs is advantage of industry and academic co-operation. With the society to advocate health condition learned from perspiration contribute people's health promotion.

## Project Background

S.Nakamura

Shinshu Univ. Sch. of Med. and Nagano Nat'l college of tech. developed the perspiration meter and was looking for a company that could develop it as a commercialized product. A company that was looking for new business. Both sides decided to start a new venture.

## Funding History

With the company cooperation the unit using moisture sensor has received the medical equipment approval and has medical equipment producing authorization.

1.1989~1993: Scholarship donation

## Reference difference method

2. 2001: Consignment study

## I ntellectual property protection

## 発汗計の測定原理

The company has already applied 10 patents and granted 6 such as 1. moisture vaporizing volume measuring device (patent no. 355993). 2. Subdermal moisture and skin moisture vaporizing volume measuring device (patent no. 3600959).

3. Perspiration meter(patent no. 3711521)

## Turning point in the Project

○Important to pursuit new things and on-site understanding

○With patent and the Society’s activity not allow followers

○No matter how excellent the product if the product does not sell it is merely a piece of block.
