For the design of in-ear fitness sensors helping to improve training method for all kind of athletes. This device can measure the pulse and body temperature with the highest precision. All measured data can be transferred to a smartphone or watch and can be evaluated after training or competition.
Battery challenge
Since these devices are determined for professional fitness use, high robustness and reliability of the cell itself must be given. The endurance cycle life performance will meet the
customers requirement of a high performance device for every day.

Technical solution
The round flat form factor of the CoinPower CP1254 fits perfectly in to the dedicated shape of the whole device. The cell has two very flat tags (0.2mm) on both faces in order to keep the entire construction very thin. These are connected directly to the electronics of the device. With this concept it was possible to achieve a slim design overall.
Lithium Button Cell – CoinPower
