In vivo tests show EnerChip batteries are biologically safe for all applications
May 15, 2013 // Paul Buckley
At the PCIM Europe exhibition Cymbet Corporation has revealed successful results of in vivo biocompatibility feasibility studies that were conducted to evaluate the biological safety of the EnerChip Rechargeable Solid State Battery.
EnerChip bare die batteries were crushed and combined into a saline solution which was introduced into an in vivo test setting. No ill effects were recorded nor were any test article related lesions observed in this study.
The in vivo test results reinforce similar findings from Cymbet’s July 2012 in vitro studies in which EnerChip bare die battery samples were gamma sterilized and evaluated using two in vitro test methods for cytotoxicity and the EnerChips demonstrated 100% non-cytotoxicity.
Cymbet EnerChip solid state batteries are fabricated using standard semiconductor manufacturing processes using patented construction techniques. One of the most rigorous ways to test the intrinsic biological safety of the EnerChip battery is to introduce crushed EnerChip bare die into in vivo test settings. Crushing the battery replicates the case of an EnerChip-powered implanted medical device that is catastrophically destroyed. In this trauma situation, the EnerChip battery components would be exposed directly to the in vivo setting. The results of this in vivo testing showed no harmful effects from having the crushed EnerChips in the body.
EnerChip batteries have the same handling and die attach mechanisms as the other Integrated Circuits found in electronic devices. This makes EnerChips ideal for co-packaging with other ICs to create advanced Systems in Package (SIP) devices. EnerChips are also packaged in standard plastic DFN semiconductor packages that ship on tape and reel. EnerChip solid state batteries are the ideal solution as they address: RoHS, China RoHS, REACH, CE Mark, UL-Underwriters Laboratory, JEDEC IC Packaging Standards, IEC, NEMA/ANSI, UN Air Safety Regulations, WEEE Directive, Battery Directive, MSDS and OSHA Information, End-of-Life Disposal Instructions and Biocompatibility Standards.
EnerChip rechargeable solid state batteries are available from Cymbet global distribution partners including: Avnet Abacus, Farnell, Element14, RS, DigiKey, Mouser and others.
