Next generation smart patch

Flexible, wearable, smart skin patches -in many ways they act as the ultimate wearable electronic devices, augmenting the wearer with minimal encumbrance. Provide maximum comfort with a sustainable solution through innovative energy supply with our rechargeable CoinPower cells.

Beside the actual vital parameters, the next generations of smart patches will also measure complex values, which in addition to dementia also include pain, dizziness, incontinence and exhaustion. The main target of the treatment is increasingly aimed at measuring as contactless as possible in order to increase the patient's well-being.

 

Battery challenge

Highest energy density, robustness and maximum housing thickness of 4 mm of the battery cell is decisive to user acceptance design shape and therefore gets highest design attention.

Technical Solution

The round flat form factor, the robust stainless steel housing and high energy density of the CoinPower A4 generation fits perfectly in to the dedicated shape of your medical assistant. With its patented cells design, VARTA CoinPower offers the perfect energy density with highest safety. Low weight and a broad range of cell sizes allow flexible design shaping and keeps the patches thin – perfect for comfortable user experience. For example look at our CP1240 A4 cell.
